Preventing Gummy Texture When Using a Large 225g Sourdough Discard Dose in Crispy Discard Pan Pizza Crust
Gluten development in crispy leftover starter pan pizza crust is already partly done for you. The 112.5g of pre-fermented flour inside 225g of leftover starter has a shortened protein network, which is why the same mixing time that would be needed for a 400g fresh-flour batter now produces a slack, tender result instead of a tough one.
Fat is your lever against spread. Because the leftover starter contributes 112.5g of extra water to a 400g flour base, the crispy leftover starter pan pizza crust batter is more hydrated than the original recipe 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 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 crispy discard pan pizza crust recipe calls for.
- Mix Discard into Flour (287.5g): Toss 287.5g of flour with the 225g of discard until every lump is coated.
- Add Liquid Gradually (157.5g): Pour in 157.5g of lukewarm 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 crispy discard pan pizza crust to 500°F (260°C) for 12–15 min.
