A jar of sourdough discard isn't waste — it's the start of pancakes, crackers, focaccia, scones, banana bread, and pizza. We've collected 25 of our favourite UK home-baker recipes for sourdough discard, organised by how old your discard is and how much time you have. Whether you've got 30 minutes and a fresh feed, or a week-old jar with a vinegary edge, there's something here to bake today.
Twenty-five recipes. One jar of discard. Zero waste.
Why your sourdough discard is actually useful
What discard is and where it comes from
What's the difference between sourdough starter and discard?
A sourdough starter is the living, recently-fed culture you bake bread with. Sourdough discard is the older portion of that same starter you remove before each new feed, to stop the jar overflowing and to keep the microbial balance healthy. Starter is alive and rising; discard is more or less paused. They are the same mixture at different points in its lifecycle.
Every time you feed your starter, you remove most of it first — otherwise the jar would double in volume each feed. That removed portion is the discard. If you're still building a starter, that long-form pillar walks the build. The five starter kits we ship include enough flour for the first ten feeds, so you'll generate your first discard inside a week.
The flavour it brings to a bake
Fresh discard tastes faintly yoghurty and sweet. Week-old discard tastes like cider. Two-week-old discard tastes like pickled apple. The shift is two acids doing the work: lactic acid (smooth, yoghurt-like, builds early) and acetic acid (sharp, vinegar-like, builds in the cold over time). The flavour pairs differently in sweet vs savoury — fresh discard brightens pancakes and brownies; older discard makes a cracker taste like a proper cracker.
Why home bakers throw away 100g+ per week — and why they shouldn't
The maths: a 50 g starter fed daily at 1:1:1 generates roughly 100 g of discard per feed. Over a week that's 700 g — about a loaf and a half's worth of flour. WRAP UK estimates UK households throw away 4.5 million tonnes of edible food a year. Sourdough discard is a small but very symbolic place to push back. Reframe it: discard isn't a problem to solve, it's an opportunity to bake more.
How to organise your discard so you actually use it
The right jar (and why airtight is wrong)
Glass jar, loose-fitting lid (never airtight — CO₂ escapes that way), 500 ml–1 L capacity. Metal lids are fine as long as the discard isn't touching them directly. Plastic is fine for short-term storage. What matters is that gas can escape.
Where it lives — fridge, counter, freezer
- Fridge (4°C or below) — default. Keeps up to 2 weeks per FSA refrigerated-dough guidance.
- Counter — a few hours only. Discard at room temp ferments fast and turns sour quickly.
- Freezer — flat in a freezer bag, up to 3 months at -18°C. Defrost overnight in the fridge.
The "stacking" method — pouring in fresh discard on top of old
The simple system: one jar, top up after each feed, don't try to separate "old" from "new". The whole jar gets tangier over time. Use accordingly — fresh-skewed for breakfast bakes, mature-skewed for crackers and pizza dough.

Breakfast bakes (with discard 0–3 days old)
1. Fluffy sourdough discard pancakes
Buttermilk-style fluffy pancakes that take 15 minutes from cracking the egg. The discard adds a faint yoghurty tang the supermarket mix can't fake. The full method, including the dairy-free swap, is at the full pancake recipe.
2. Crispy-edged sourdough discard waffles
Crispy on the outside, just-cooked-custard in the middle. Better than the buttermilk-only version — the discard adds a buttermilk tang you can't fake.
Ingredients (UK): 200 g discard / 1 egg, beaten / 60 g plain flour / 25 g caster sugar / 1 tsp bicarbonate of soda / pinch fine sea salt / 30 g salted butter, melted (or sunflower oil for dairy-free) / 100 ml whole milk (or oat milk).
Method: Whisk discard, egg, milk, butter. Add dry ingredients and stir until just combined — small lumps are fine. Pour into a hot greased waffle iron and cook 4–5 minutes per batch. Pairs with maple syrup, crisp streaky bacon, strong tea.
3. Sourdough discard scones (sweet or savoury)
A scone with a tang. Butter and jam, or strong cheddar and chutney.
Ingredients (UK): 100 g discard / 250 g self-raising flour / 50 g cold salted butter, cubed / 50 g caster sugar (sweet) OR 50 g grated mature cheddar (savoury) / 100 ml whole milk / 1 egg yolk to glaze.
Method: Rub butter into flour. Stir in sugar/cheese. Mix in discard and milk to a just-combined dough. Roll to 3 cm, cut 6 rounds, glaze, bake 220°C for 12–15 minutes.
4. Sourdough discard crumpets
Proper crumpet holes need a thinner batter than the supermarket version — discard does the work.
Ingredients (UK): 200 g discard / 150 g plain flour / 250 ml warm whole milk / 1 tsp caster sugar / 1 tsp bicarbonate of soda / ½ tsp fine sea salt.
Method: Whisk to a thick pancake-batter consistency. Rest 20 minutes. Heat a heavy frying pan medium-low, brush with butter, set crumpet rings, ladle batter two-thirds full. Cook 6–8 minutes until the holes break and the top is dry, then flip 1 minute. Salted butter pools in the holes.
5. Discard porridge swirl
Stir 2 tbsp of fresh discard into hot finished porridge with a knob of butter and a drizzle of honey — buttermilk tang without buttermilk.
Bread bakes (with discard 1–7 days old)
6. No-knead Dutch oven discard loaf
Our no-knead overnight loaf — cold ferment, hot pot, the works. Our no-knead discard loaf walks the full method, including UK Dutch-oven substitutes for under £20.
7. Sourdough discard sandwich tin loaf
Softer than a country loaf, taller too, with a tin shape your family will recognise from the supermarket shelf.
Ingredients (UK): 200 g discard / 500 g strong white bread flour / 280 ml warm water / 10 g fine sea salt / 7 g instant yeast (yes, both — discard is for flavour here, yeast does the lift) / 25 g salted butter, softened.
Method: Mix flour, yeast, salt. Add discard, water, butter. Knead 8 minutes. First rise 1 hour. Shape into a 900 g tin, second rise 45 minutes. Bake 200°C for 30 minutes.
8. Quick discard focaccia
Crisp olive-oil bottom, dimpled top, rosemary and flaky salt.
Ingredients (UK): 250 g discard / 400 g strong white bread flour / 320 ml warm water / 8 g fine sea salt / 5 g instant yeast / 80 ml extra-virgin olive oil + extra for the tray / fresh rosemary / flaky sea salt.
Method: Mix dough, rise 1 hour, transfer to oiled tray, dimple with fingers, second rise 30 minutes, top with rosemary and salt, bake 220°C for 22 minutes.
9. Discard soda bread (no overnight prove)
Crumbly, tangy, ready before lunch — the loaf for the day you forgot to start one.
Ingredients (UK): 200 g discard / 350 g plain flour (or half wholemeal) / 1 tsp bicarbonate of soda / 1 tsp fine sea salt / 280 ml buttermilk (or 280 ml whole milk + 1 tbsp lemon juice, left 5 minutes).
Method: Mix dry. Add discard and buttermilk. Bring together to a rough dough — do not knead. Shape into a round, cross-cut the top, bake 220°C for 30–35 minutes.
10. Discard flatbread on the hob
200 g discard + 150 g plain flour + ½ tsp salt → soft dough → divide into 4 → roll thin → cook 2 minutes a side in a dry hot pan.
Crackers and savoury snacks (with discard 3–14 days old)
11. Classic sourdough discard crackers
Shatter-crisp, snappy, salty. Our full cracker recipe covers the paper-thin rolling trick and how to keep them crisp for a fortnight.
12. Herb and sea-salt crackers
Snappy, savoury, the cracker you bring to a cheese board and someone asks for the recipe.
Ingredients (UK): 200 g discard / 80 g plain flour / 30 g extra-virgin olive oil / 2 tbsp chopped fresh rosemary and thyme / 1 tsp flaky sea salt + extra for topping.
Method: Mix to a smooth dough. Roll between two sheets of baking paper as thin as you can — almost translucent. Score into squares. Top with flaky salt. Bake 180°C for 18–22 minutes until deeply golden.
13. Seeded crackers with poppy, sesame, flax
Same base as herb crackers; swap herbs for 3 tbsp mixed seeds pressed into the dough before rolling.
14. Cheddar and black-pepper crackers
These are the ones we make when the jar tips over a week old and the smell is sharp enough to clear the kitchen.
Ingredients (UK): 200 g discard / 80 g plain flour / 75 g mature cheddar, finely grated / 1 tsp coarsely cracked black pepper / ½ tsp fine sea salt / 30 g extra-virgin olive oil.
Method: Mix to a smooth dough. Roll thin. Score. Bake 180°C 18 minutes.
Clara's go-to: "When the discard tips over a week, I add extra cheddar and black pepper and don't look back. They keep in a tin for a fortnight — if they last that long."
15. Discard cheese straws
Same dough as the cheddar crackers but rolled into a rectangle, sprinkled with parmesan, folded once, sliced into strips, twisted, and baked 180°C for 15 minutes.
Sweet bakes (with discard 1–10 days old)
16. Sourdough discard banana bread
The crumb is denser and tangier than the standard recipe — the banana sweetness lands harder against the discard's acid.
Ingredients (UK): 200 g discard / 3 very ripe bananas (about 300 g peeled) / 150 g caster sugar / 100 g salted butter, melted / 2 eggs / 250 g plain flour / 1 tsp bicarbonate of soda / 1 tsp ground cinnamon / pinch fine sea salt / optional: 75 g chopped walnuts or dark chocolate chunks.
Method: Mash bananas. Whisk in sugar, butter, eggs, discard. Fold in dry ingredients. Pour into greased tin. Bake 180°C for 50–55 minutes.
17. Discard fudge brownies
The acidity in the discard sharpens the chocolate — these are darker, less sweet, more grown-up.
Ingredients (UK): 100 g discard / 200 g dark chocolate (70%), chopped / 200 g salted butter / 200 g caster sugar / 100 g light brown muscovado / 3 eggs / 100 g plain flour / 30 g cocoa powder / ½ tsp fine sea salt.
Method: Melt chocolate + butter. Whisk in sugars then eggs. Fold in discard, flour, cocoa, salt. Pour into lined tin. Bake 170°C for 25–28 minutes — the middle should still wobble.
18. Cinnamon-swirl discard rolls
Pillowy, glossy, the cinnamon swirl tight.
Dough: 200 g discard / 400 g strong white flour / 50 g caster sugar / 7 g instant yeast / 1 tsp fine sea salt / 200 ml warm whole milk / 60 g salted butter, melted / 1 egg. Filling: 80 g salted butter, soft / 100 g light brown muscovado / 2 tbsp ground cinnamon. Glaze: 100 g icing sugar + 30 ml whole milk.
Method: Make dough, prove 1 hour. Roll to a 40×30 cm rectangle. Spread filling. Roll up tight. Cut 9 slices. Second prove 45 minutes. Bake 180°C for 22 minutes. Glaze warm.
19. Discard digestive-style biscuits
100 g discard + 150 g wholemeal flour + 100 g cold butter + 50 g muscovado + pinch salt. Rub together. Roll, cut, prick, bake 170°C 20 minutes.
20. Discard chocolate-chip cookies
Standard cookie dough with 50 g discard subbed in for some of the butter — gives a chewy edge and a faint tang against the chocolate.
Dinner bakes (with discard 3–14 days old)
21. Sourdough discard pizza dough (Friday-night version)
Our overnight discard pizza dough — with the cold-retard schedule and the Ooni-friendly hydration — is at our discard pizza dough.
22. Discard pasta dough
200 g discard + 300 g "00" flour + 2 eggs + 1 tsp salt + 1 tbsp olive oil. Knead 10 minutes. Rest 30 minutes wrapped. Roll thin in a pasta machine or by hand. Cut as you like.
23. Discard dumpling wrappers
150 g discard + 200 g plain flour + ½ tsp salt + 50 ml warm water → smooth dough → rest 20 minutes → roll into rounds → fill with whatever you've got.
24. Discard naan-style flatbread
200 g discard + 200 g plain flour + ½ tsp salt + 50 ml warm milk + 1 tbsp yoghurt. Cook in a very hot dry pan or under a hot grill.
25. Discard Yorkshire pudding
The discard adds a faint buttermilk note. Higher rises, crisper edges than the standard recipe.
Ingredients (UK): 100 g discard / 2 large eggs / 100 g plain flour / 150 ml whole milk / ½ tsp fine sea salt / beef dripping or sunflower oil for the tin.
Method: Whisk discard, eggs, milk, flour, salt to a smooth batter. Rest 30 minutes. Heat tin with 1 tsp oil per hole at 220°C until smoking. Pour in batter. Bake 20–25 minutes without opening the oven.
When discard is too old to use
The smell-and-look test (and the three warning signs)
Three signs that mean bin it:
- Pink, orange or fuzzy mould on the surface — bin it.
- Acetone or paint-stripper smell that doesn't go after a stir — bin it.
- Pink streaks through the discard — bin it.
Vinegary sharp smell is not a warning sign — it's normal at 7+ days. A grey "hooch" liquid on top is also normal — pour it off or stir it in.
FSA storage windows — how long is actually safe
How long can I keep sourdough discard?
Sourdough discard keeps for up to two weeks in a sealed jar in the fridge at 4°C or below, in line with FSA guidance on refrigerated fermented dough. Pour fresh discard on top of older discard with no problem — it just gets tangier. Beyond two weeks the discard becomes too acidic and yeast activity falls away, but it is rarely unsafe — it is unpleasant, not dangerous, unless visible mould or pink streaks appear. Frozen flat at -18°C, discard keeps for up to 3 months. Defrost overnight in the fridge.
What to do with truly too-old discard
Compost layer ratios
Discard is a "green" (nitrogen-rich) layer. Mix with browns (cardboard, autumn leaves, sawdust) at roughly 1:3 by volume. Don't dump 500 g of discard into one spot — spread it through.
Stockpot booster
1–2 tablespoons of old discard at the start of a chicken or vegetable stock adds umami depth. Doesn't make the stock sour at that dose. (Trick we picked up from Tartine.)
Chicken or duck feed (if you keep them)
A handful of old discard mixed into layers' feed is a fine probiotic boost. Daily, not more. Don't feed mouldy discard.

Frequently asked questions
What should I do with my sourdough discard?
Sourdough discard is the portion of starter you'd normally throw away before each feed — and almost any baked good benefits from it. Use fresh discard (0–3 days old) for pancakes, waffles, and scones. Use 3–7 day-old discard for bread and focaccia. Use 7–14 day-old discard for crackers, pizza dough, and flatbreads. The older it gets, the tangier the result.
How long can I keep sourdough discard?
Sourdough discard keeps for up to two weeks in a sealed jar in the fridge at 4°C or below, in line with FSA guidance on refrigerated fermented dough. Pour fresh discard on top of older discard with no problem — it just gets tangier. Beyond two weeks the discard becomes too acidic and yeast activity falls away, but it is rarely unsafe — it is unpleasant, not dangerous, unless visible mould or pink streaks appear.
Can I use sourdough discard instead of yeast?
Sourdough discard is not a reliable substitute for commercial yeast on its own. Refrigerated discard older than 24 hours has very little leavening power left — the yeast slows almost to a stop in the cold. For bread that needs to rise, pair discard with either a fresh active starter, commercial baker's yeast, or chemical leaveners like bicarbonate of soda. Discard's job is flavour and structure, not lift.
What's the difference between sourdough starter and discard?
A sourdough starter is the living, recently-fed culture you bake bread with. Sourdough discard is the older portion of that same starter you remove before each new feed, to stop the jar overflowing and to keep the microbial balance healthy. Starter is alive and rising; discard is more or less paused. They are the same mixture at different points in its lifecycle.
Is sourdough discard healthy?
Sourdough discard carries the same nutritional profile as the flour it was made from — typically wholemeal or strong white — plus some pre-digestion of starches by the fermentation. There is no published evidence that small amounts of discard in a recipe deliver the gut-health benefits of a long-fermented sourdough loaf, but it is no less healthy than the equivalent flour. Discard is not a health food on its own; it is flavour and texture.
What can I do with sourdough discard in the UK?
UK home bakers can make pancakes, crumpets, scones, soda bread, focaccia, cheddar crackers, Yorkshire puddings, banana bread, brownies, pizza, and flatbreads from sourdough discard. The 25-recipe collection above uses UK supermarket ingredients — wholemeal flour, salted butter, golden syrup, double cream — and UK measurements in grams and millilitres. WRAP UK estimates households throw away 4.5 million tonnes of edible food a year; discard is an easy place to start reducing yours.
Can I freeze sourdough discard?
Yes — spread it thin in a freezer bag, freeze flat at -18°C, and it keeps for up to 3 months. Defrost overnight in the fridge before use. Frozen discard loses most of its yeast activity but keeps its flavour, so it suits pancakes, crackers and brownies, not bread that needs to rise on the discard alone.
Why does my sourdough discard smell like vinegar?
The vinegar smell comes from acetic acid building up as the discard ages in the fridge — the cold slows lactic-acid-producing bacteria but acetic-acid producers stay active. By day 7 most discard smells distinctly sharp. It is normal, not a sign of spoilage. Use it for crackers, pizza dough, or savoury bakes where the acidity is a feature, not a problem.
Do I have to discard at every feed?
No — small starters (50 g or under) fed at 1:3:3 ratios can be fed without discarding, since the math works out. But most home bakers run larger starters and feed daily, which generates 100–200 g of discard per feed. The 25 recipes above turn that "waste" into the rest of your week's baking.
