How to Use 150g (0.63 Cups) Sourdough Discard in Rosemary Olive Oil Discard Crackers
Zero-waste baker's math to fold 150g of unfed sourdough discard into rosemary olive oil discard crackers without making the batter gummy or runny.
Here is the whole conversion in one line: 150g of 100% hydration discard equals 75g of flour plus 75g of water, so a Rosemary Olive Oil Discard Crackers mix moves from 200g / 140g to 125g / 65g once the discard is in. Add 0.8g of sodium bicarbonate to neutralise the acid and give the lift, then cook at 325°F (165°C) for 30–35 min.

Food Chemistry: Why 150g of Unfed Discard Improves Rosemary Olive Oil Discard Crackers
Enzymatic tenderisation is cumulative, and 150g is a meaningful dose. The protease activity that has already shortened the gluten chains inside 150g of leftover starter keeps working for as long as the batter rests, so rosemary olive oil leftover starter crackers dough mixed with leftover starter rewards a shorter rest than a conventional batter.
Fat is your lever against spread. Because the discard contributes 75g of extra water to a 200g flour base, the rosemary olive oil discard crackers 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 Rosemary Olive Oil Discard Crackers with 150g Sourdough Discard
- Recalculate the Salt: Your 150g of discard was salted when it was last fed, so use slightly less salt than the original rosemary olive oil discard crackers recipe calls for.
- Mix Discard into Flour (125g): Toss 125g of flour with the 150g of discard until every lump is coated.
- Add Liquid Gradually (65g): Pour in 65g of water & olive oil a little at a time until the batter comes together.
- Add 0.8g Soda and Cook: Stir in the bicarbonate, let it foam briefly, then take the rosemary olive oil discard crackers to 325°F (165°C) for 30–35 min.
Frequently Asked Questions for This Sourdough Discard Gram Converter Spec
Does the type of rosemary olive oil discard crackers matter when using 150g of discard?
Yes. High-moisture batters like rosemary olive oil discard crackers tolerate a large discard dose because the extra 75g of water is offset by fat and sugar, while lean cracker doughs need the discard kept under about 10% of the flour weight.
Can I use a 50% hydration discard instead of 100% in this rosemary olive oil discard crackers recipe?
Yes, but the deductions change completely: at 50% hydration, 150 grams of discard carries 100g of flour instead of 75g, so you would deduct that much more flour and correspondingly less liquid.
Can I freeze rosemary olive oil discard crackers made with 150 g of discard?
Yes, and discard actually freezes well because the pre-fermented flour is already partly broken down. Mix to the point of combining, then freeze without the bicarbonate so the acid and base do not react before you bake.
