How to Use 75g (0.31 Cups) Sourdough Discard in Chewy Sourdough Discard Bagels
Got a small 75g jar remnant? Exact flour and liquid deductions to fold 75g of unfed discard into chewy sourdough discard bagels for tender flavor.
Folding 75g (0.31 cups) of 100% hydration leftover starter into Chewy Sourdough Discard Bagels injects 37.5g pre-fermented flour and 37.5g water. To preserve batter viscosity on a 500g flour / 285g warm water base, weigh 462.5g fresh flour, 247.5g warm water, and 0.4g sodium bicarbonate before cooking at Boil 60s + 425°F for 20 min.

Why Even a Small 75g Sourdough Discard Addition Tenderizes Chewy Sourdough Discard Bagels
Retention matters. Discard that has been fed recently carries a higher concentration of active yeast, so 75g of young discard will begin proving the chewy sourdough discard bagels batter before you even add baking powder, while 75g of neglected discard contributes acidity without any gas. Both behave identically in a scale but not in a bowl.
Fat is your lever against spread. Because the discard contributes 37.5g of extra water to a 500g flour base, the chewy sourdough discard bagels 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 Chewy Sourdough Discard Bagels with 75g Sourdough Discard
- Whisk 75 g Discard Into Wet Ingredients: Combine 75 g of discard with 247.5g warm water (down from 285g) until homogeneous.
- Adjust Dry Flour & Leavening (462.5g): Weigh 462.5g flour (-37.5g) and whisk in 0.4g baking soda.
- Rest Before Cooking (10 minutes): Let the acid in the 75 g of discard finish reacting with the bicarbonate so the batter tastes clean rather than sharp.
- Cook at Boil 60s + 425°F for 20 min: Fold wet and dry mixes gently so the 75 g discard formula stays light.
Frequently Asked Questions for This Sourdough Discard Gram Converter Spec
How much baking soda should I add with 75g of discard?
Around 1.2g (¼ tsp) per 100g of discard keeps the acidity mild without leaving a soapy aftertaste, which makes 0.4g the right dose for 75g of discard in chewy sourdough discard bagels.
Does 75g of discard leaven chewy sourdough discard bagels on its own?
Unfed fridge discard adds tang and tenderness to chewy sourdough discard bagels, while the recipe's baking powder, the 0.4g of sodium bicarbonate, or commercial yeast provides the primary rapid leavening at Boil 60s + 425°F for 20 min.
Can I freeze chewy sourdough discard bagels made with 75 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.
