Big-Batch 400g (1.67 Cups) Sourdough Discard Crispy Discard Pan Pizza Crust Conversion & Acid Balance
High-discard jar clearout math: replacing 200g flour and 200g lukewarm water while neutralizing sourness with 2g baking soda.
Treat discard as an ingredient with a declared weight rather than a freebie. 400g of it brings 200g flour and 200g water into crispy discard pan pizza crust, which means the base formula's 400g of flour and 270g of lukewarm water must drop to 200g and 70g. 2g of soda balances the acid. Cook at 500°F (260°C) for 12–15 min.

Zero-Waste Crispy Discard Pan Pizza Crust Math — 400g Discard Decomposed by Hydration
Soda column assumes the balanced 1.2g per 100g of discard dose; halve it for a pronounced tang.
| Hydration Level | Discard Flour Content | Discard Water Content | Remaining Flour | Remaining Lukewarm Water | Soda Neutraliser |
|---|---|---|---|---|---|
| 50% starter, 400g serving [Primary] | minus 266.7g flour | minus 133.3g liquid | 133.3g flour left | 136.7g liquid left | 2g NaHCO3 |
| 100% starter, 390g serving Leaner Dough | minus 195g flour | minus 195g liquid | 205g flour left | 75g liquid left | 2g NaHCO3 |
| 125% starter, 410g serving Wetter Dough | minus 182.2g flour | minus 227.8g liquid | 217.8g flour left | 42.2g liquid left | 2.1g NaHCO3 |
| 75% starter, 380g serving Tight Dough | minus 217.1g flour | minus 162.9g liquid | 182.9g flour left | 107.1g liquid left | 1.9g NaHCO3 |
| 100% starter, 420g serving Loose Dough | minus 210g flour | minus 210g liquid | 190g flour left | 60g liquid left | 2.1g NaHCO3 |

Preventing Gummy Texture When Using a Large 400g Sourdough Discard Dose in Crispy Discard Pan Pizza Crust
Osmotic balance matters more in discard batters than in bread dough. The 2g of bicarbonate raises the pH of the crispy discard pan pizza crust mix just enough that the 8g of residual acid no longer depresses gluten formation, which is what allows the 200g of remaining flour to hydrate fully instead of clumping.
Fat is your lever against spread. Because the discard contributes 200g of extra water to a 400g flour base, the crispy discard pan pizza crust batter is more hydrated than the original formula intended; browning the butter or adding an extra fat locks that water into an emulsion so the finished bake spreads less.
How to Mix Crispy Discard Pan Pizza Crust with 400g Sourdough Discard
- Recalculate the Salt: Your 400g of discard was salted when it was last fed, so use slightly less salt than the original crispy discard pan pizza crust recipe calls for.
- Mix Discard into Flour (200g): Toss 200g of flour with the 400g of discard until every lump is coated.
- Add Liquid Gradually (70g): Pour in 70g of lukewarm water a little at a time until the batter comes together.
- Add 2g Soda and Cook: Stir in the bicarbonate, let it foam briefly, then take the crispy discard pan pizza crust to 500°F (260°C) for 12–15 min.
Frequently Asked Questions for This Sourdough Discard Gram Converter Spec
Can I use a 50% hydration discard instead of 100% in this crispy discard pan pizza crust recipe?
Yes, but the deductions change completely: at 50% hydration, 400 grams of discard carries 267g of flour instead of 200g, so you would deduct that much more flour and correspondingly less liquid.
What happens if I add 400g of discard to a recipe with no leavening at all?
Nothing will lift, because a fed starter's gas is mostly gone by the time it becomes discard. You still need the 2g of bicarbonate or a full measure of baking powder to get the rise at 500°F (260°C) for 12–15 min.
How much baking soda should I add with 400g of discard?
Around 1.2g (¼ tsp) per 100g of discard keeps the acidity mild without leaving a soapy aftertaste, which makes 2g the right dose for 400g of discard in crispy discard pan pizza crust.
