Big-Batch 225g (0.94 Cups) Sourdough Discard Same-Day Sourdough Discard Focaccia Conversion & Acid Balance
High-discard jar clearout math: replacing 112.5g flour and 112.5g warm water while neutralizing sourness with 1.1g baking soda.
Folding 225g (0.94 cups) of 100% hydration leftover starter into Same-Day Sourdough Discard Focaccia injects 112.5g pre-fermented flour and 112.5g water. To preserve batter viscosity on a 500g flour / 400g warm water base, weigh 387.5g fresh flour, 287.5g warm water, and 1.1g sodium bicarbonate before cooking at 450°F (230°C) for 22–25 min.

Preventing Gummy Texture When Using a Large 225g Sourdough Discard Dose in Same-Day Sourdough Discard Focaccia
Maillard browning depends on the sugar pool, and discard feeds that pool slowly. Because 225g of discard has already consumed most of its own maltose, the 500g of fresh flour in the same-day sourdough discard focaccia recipe must supply the reducing sugars for crust colour at 450°F (230°C) for 22–25 min — so a dough with too much discard browns pale and unevenly.
Browned butter solves two problems at once for same-day sourdough discard focaccia. It evaporates a meaningful fraction of the butter's own water while producing emulsified milk solids, which both reduces spread and adds a nutty depth that no amount of sourdough acidity can imitate.
How to Mix Same-Day Sourdough Discard Focaccia with 225g Sourdough Discard
- Recalculate the Salt: Your 225g of discard was salted when it was last fed, so use slightly less salt than the original same-day sourdough discard focaccia recipe calls for.
- Mix Discard into Flour (387.5g): Toss 387.5g of flour with the 225g of discard until every lump is coated.
- Add Liquid Gradually (287.5g): Pour in 287.5g of warm water a little at a time until the batter comes together.
- Add 1.1g Soda and Cook: Stir in the bicarbonate, let it foam briefly, then take the same-day sourdough discard focaccia to 450°F (230°C) for 22–25 min.
Frequently Asked Questions for This Sourdough Discard Gram Converter Spec
How long should I rest the same-day sourdough discard focaccia batter after mixing in discard?
Ten minutes is the sweet spot at room temperature. It lets the 1.1g of bicarbonate finish neutralising the discard's acid while the 387.5g of flour hydrates around the 287.5g of liquid.
Can I use a 50% hydration discard instead of 100% in this same-day sourdough discard focaccia recipe?
Yes, but the deductions change completely: at 50% hydration, 225 grams of discard carries 150g of flour instead of 112.5g, so you would deduct that much more flour and correspondingly less liquid.
Why is my same-day sourdough leftover starter focaccia spreading more than the original recipe after adding leftover starter?
Almost always because the 112.5g of water inside 225g of leftover starter was not deducted. Correct the liquid to 287.5g, and brown the butter or add an extra fat to lock the remaining moisture.
