How to Use 80g (0.33 Cups) Sourdough Discard in Chewy Sourdough Discard Bagels
Got a small 80g jar remnant? Exact flour and liquid deductions to fold 80g of unfed discard into chewy sourdough discard bagels for tender flavor.
Most failed discard batters fail on arithmetic, not chemistry. 80 g of discard is not a free ingredient — it is 40g flour and 40g water delivered together. Deduct both from the 500g / 285g chewy sourdough discard bagels base to get 460g / 245g, add 0.4g of sodium bicarbonate for lift, and finish at Boil 60s + 425°F for 20 min.

Flour, Liquid & Soda Deductions for 80g of Discard in Chewy Sourdough Discard Bagels
Soda column assumes the balanced 1.2g per 100g of discard dose; halve it for a pronounced tang.
| Discard Hydration % | Flour Carried In | Water Carried In | Fresh Flour Needed | Fresh Warm Water Needed | Bicarbonate Buffer |
|---|---|---|---|---|---|
| 70g @ 75% [Exact Target] | -40g flour | -30g Warm Water | = 460g flour | = 255g Warm Water | +0.4g soda |
| 100g @ 100% Alt Row A | -50g flour | -50g Warm Water | = 450g flour | = 235g Warm Water | +0.5g soda |
| 80g @ 125% Alt Row B | -35.6g flour | -44.4g Warm Water | = 464.4g flour | = 240.6g Warm Water | +0.4g soda |
| 60g @ 50% Alt Row C | -40g flour | -20g Warm Water | = 460g flour | = 265g Warm Water | +0.3g soda |
| 90g @ 100% Alt Row D | -45g flour | -45g Warm Water | = 455g flour | = 240g Warm Water | +0.5g soda |

Why Even a Small 80g Sourdough Discard Addition Tenderizes Chewy Sourdough Discard Bagels
The acid load arrives with the flour, not the water. Roughly 2 grams of lactic and acetic acid ride along inside 80g of leftover starter, and that is exactly why 0.4g of sodium bicarbonate belongs in the formula: it converts those acids into their much milder sodium salts while releasing the CO2 that lifts the batter at Boil 60s + 425°F for 20 min.
Scaling the discard changes the soda proportionally. Every additional 100g of discard needs another 1.2g of sodium bicarbonate, so at 80g you are working with 0.4g rather than a flat teaspoon, and the balance shifts further as the dose climbs.
How to Mix Chewy Sourdough Discard Bagels with 80g Sourdough Discard
- Recalculate the Salt: Your 80g of discard was salted when it was last fed, so use slightly less salt than the original chewy sourdough discard bagels recipe calls for.
- Mix Discard into Flour (460g): Toss 460g of flour with the 80g of discard until every lump is coated.
- Add Liquid Gradually (245g): Pour in 245g of warm water a little at a time until the batter comes together.
- Add 0.4g Soda and Cook: Stir in the bicarbonate, let it foam briefly, then take the chewy sourdough discard bagels to Boil 60s + 425°F for 20 min.
Common Scaling & Troubleshooting Questions (-40g)
Can I use 80g of active bubbly starter instead of unfed leftover starter for chewy sourdough leftover starter bagels?
Yes. Active starter and unfed leftover starter carry the same hydration by weight (40g flour + 40g water), though active starter will also begin proving the batter. Always measure 80g on a digital scale rather than by cup volume (0.33 cups).
Can I make this recipe with 40g of discard instead?
Halve every weight: 20g of flour and 20g of liquid come out of the base recipe, and you need 0.4g of sodium bicarbonate.
Will 80 g of discard make chewy sourdough discard bagels taste sour?
Only if the acid is left un-neutralised. The 0.4g of bicarbonate reacts with the roughly 2g of acid inside 80 g of discard, converting it to mild sodium salts and leaving a pleasant background tang.
