Every time you feed your starter, you discard a portion to keep the volume manageable. That discard is just flour and water that's been fermented for hours or days — slightly sour, slightly tangy, full of flavour. It is not waste. It is the most useful by-product in baking.
Discard adds depth to almost any flour-based recipe. It works in pancakes, in brownies, in pasta, in pizza dough, in scones, in waffles, in cake, in crackers. Most British baking traditions can absorb it without complaint — and many of them benefit. Once you start cooking with discard you stop seeing it as the by-product. It becomes the point.
A new starter being fed daily produces around 50g of discard a day. Over a week that's 350g — roughly the flour content of a small loaf. A mature starter being kept in the fridge and fed weekly produces around 50–100g a week. Either way, you have ingredient. Use it.
The two terms get used interchangeably and they shouldn't be. Active starter is starter at peak — fed within the last 4–8 hours, doubled in size, full of bubbles, ready to leaven a loaf. Discard is starter that has not been fed recently — anywhere from a day to a fortnight old. It still works in most recipes that don't depend on the discard providing rise (because old discard has very little oomph left). For rise, use baking powder, bicarbonate of soda, or whisked eggs.
Most home bakers keep an old jar in the fridge labelled "discard" and add to it at every feed. That works. Two refinements make it work better:
Use a wide-mouthed jar with a clip-top lid. Add to it after every feed, stirring the new discard into the existing pool. Label the jar with the date you started it. Keep it in the door of the fridge — not the back, where it can freeze.
It will keep for 2 weeks at fridge temperature. Past that, the smell will tell you — sharp vinegar fading into something more cheesy and unpleasant means it's time to bin and start fresh.
If you generate more discard than you use, freeze it. Two ways:
Freezer discard keeps for 3 months. Defrost overnight in the fridge before using.
| State | Storage | Best for |
|---|---|---|
| Fresh (within 24h of feed) | Counter or fridge | Anything that needs rise — crumpets, pancakes, pikelets |
| Fridge, 1–7 days | Fridge, sealed | Most discard recipes, neutral flavour |
| Fridge, 1–2 weeks (with hooch) | Fridge, sealed | Crackers, biscuits, brownies — strong sour notes welcome |
| Frozen, up to 3 months | Freezer bag/cubes | Anything once defrosted |
| Past 2 weeks at fridge temp | Bin | — |
Discard naturally smells sour, slightly cheesy, occasionally faintly of nail varnish. None of that means it's bad. The signs that it actually has spoiled:
Hooch (the brown liquid that forms on top) is not spoilage — it's a sign the starter is hungry. Stir it back in or pour it off and proceed.
Different recipes need different discard ages. Get this right and even recipes that seem unforgiving will work. Get it wrong and you'll end up with a flat crumpet or a too-sharp brownie.
| Recipe type | Best discard age | Why |
|---|---|---|
| Crumpets, pancakes, pikelets | Fresh (within 24h of feed) | Bicarb reaction with active acid produces holes/lift |
| Naan, flatbread, focaccia | Fresh to 3 days | Some lift desired but not critical |
| Brownies, cakes, scones | Any age | Lift comes from baking powder/eggs, discard adds flavour |
| Crackers, biscuits | Older = more flavour | You want depth, not rise |
| Pasta, pizza dough | 3 days+ | Deeper sourdough flavour develops |
| Discard bread loaves | Any age, plus added yeast | Discard is for flavour; commercial yeast for rise |
For when there's discard in the jar and you've got fifteen minutes between Zoom calls.
The British breakfast options. Fresh discard is best for these because the bicarb-acid reaction produces the bubbles you're after.
The discard recipes that go best with curry, dip, or olive oil.
Where discard's tang really earns its keep — it cuts through richness in a way fresh dough can't.
Older discard is actually preferable here — the deeper sour notes work brilliantly with sharp cheese.
Bread loaves where discard contributes flavour but not the rise. These all use commercial yeast or baking powder for lift.
Yes — discard is fully fermented flour-and-water. It works in any recipe that uses flour and a liquid, with adjustments to compensate for the discard's contribution to both. Most discard recipes also use chemical leaveners (baking powder, bicarb) for rise.
Up to 2 weeks in the fridge, longer in the freezer. Past 2 weeks at fridge temperature, bin it. Discard improves in flavour for the first week, then plateaus, then declines.
No. Most discard recipes use baking powder or bicarbonate of soda for lift. The discard adds flavour and tenderness, not rise.
Yes — bring it to room temperature for 15 minutes if the recipe calls for warm ingredients (cakes, batters). Otherwise straight from cold is fine.
Discard is starter that hasn't been fed recently — slightly less yeasty, slightly more sour, much less leavening power. Active starter is at peak rise, ready to leaven bread. Most discard recipes work with either, but recipes that need rise from the starter (sandwich bread, country loaves) require active starter.
Most discard recipes use 100–200g, which is what you'll generate from a single feed. If you have less, scale down; if you have more (you've been hoarding), the simplest big-batch use is sourdough crackers — they keep for two weeks in a sealed tin.
Yes — portion into ice cube trays (50g each) or flatten in freezer bags. Defrost overnight in the fridge. Keeps 3 months.
That's hooch — the alcohol-and-acid byproduct of fermentation. It's a sign your discard is hungry but not spoiled. Either stir back in (more sour flavour) or pour off (milder). Then feed.
Yes — rye discard is more active and more flavoured. Reduce other liquid in the recipe by 5–10% to compensate for rye's extra absorption.
Long fermentation (which is what discard is) reduces FODMAPs and increases mineral bioavailability. It's not dramatically different from fresh sourdough but slightly more digestible for sensitive stomachs.
