Big-Batch 225g (0.94 Cups) Sourdough Discard Rosemary Olive Oil Discard Crackers Conversion & Acid Balance
High-discard jar clearout math: replacing 112.5g flour and 112.5g water & olive oil while neutralizing sourness with 1.1g baking soda.
Scale the rosemary olive oil discard crackers formula once and you are done: 200g flour minus the 112.5g inside your 225g of discard is 87.5g, and 140g of water & olive oil minus the 112.5g it contains is 27.5g. Add 1.1g of baking soda and cook at 325°F (165°C) for 30–35 min.

Flour, Liquid & Soda Deductions for 225g of Discard in Rosemary Olive Oil Discard Crackers
The 100% hydration row is your primary target; the 50% and 125% rows show how the deduction changes with a wetter or stiffer discard.
| Discard Hydration % | Flour Carried In | Water Carried In | Fresh Flour Needed | Fresh Water & Olive Oil Needed | Bicarbonate Buffer |
|---|---|---|---|---|---|
| 50% starter, 205g serving [Anchor] | minus 136.7g flour | minus 68.3g liquid | 63.3g flour left | 71.7g liquid left | 1g NaHCO3 |
| 100% starter, 225g serving 50% Hydration | minus 112.5g flour | minus 112.5g liquid | 87.5g flour left | 27.5g liquid left | 1.1g NaHCO3 |
| 125% starter, 245g serving 75% Hydration | minus 108.9g flour | minus 136.1g liquid | 91.1g flour left | 3.9g liquid left | 1.2g NaHCO3 |
| 75% starter, 215g serving 125% Hydration | minus 122.9g flour | minus 92.1g liquid | 77.1g flour left | 47.9g liquid left | 1.1g NaHCO3 |
| 100% starter, 235g serving Standard 100% | minus 117.5g flour | minus 117.5g liquid | 82.5g flour left | 22.5g liquid left | 1.2g NaHCO3 |

Preventing Gummy Texture When Using a Large 225g Sourdough Discard Dose in Rosemary Olive Oil Discard Crackers
The acid load arrives with the flour, not the water. Roughly 5 grams of lactic and acetic acid ride along inside 225g of discard, and that is exactly why 1.1g of sodium bicarbonate belongs in the formula: it converts those acids into their much milder sodium salts while releasing the CO2 that lifts the batter at 325°F (165°C) for 30–35 min.
Do not add baking powder on top of the soda without adjusting it. The 1.1g of bicarbonate already supplies lift through gas production, so halving the baking powder in the original rosemary olive oil discard crackers recipe prevents a metallic, soapy crumb.
How to Mix Rosemary Olive Oil Discard Crackers with 225g Sourdough Discard
- Pre-weigh for Accuracy: Set out 225 grams of discard, 87.5g of flour and 27.5g of water & olive oil on the scale before you begin — discard sticks to spoons and misreads badly.
- Blend the Discard Smoothly: Work 225 grams of discard into the 27.5g of liquid with a whisk until the mixture is completely uniform, with no visible fermented lumps.
- Fold in Flour & 1.1g Soda: Add the 87.5g of sifted flour and the bicarbonate, then mix only until no dry patches survive.
- Cook to Spec (325°F (165°C) for 30–35 min): The rosemary olive oil discard crackers is ready when the centre springs back and the surface is no longer wet.
Cereal Chemistry & Bench Execution FAQs
What happens if I add 225 grams 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 1.1g of bicarbonate or a full measure of baking powder to get the rise at 325°F (165°C) for 30–35 min.
Is 225g of discard enough to make rosemary olive oil discard crackers taste different from the original recipe?
Yes. The 112.5g of pre-fermented flour softens the crumb and the roughly 5g of residual acid adds a background tang that reads clearly at 1.1g of neutralised soda.
How much baking soda should I add with 225 g of discard?
Around 1.2g (¼ tsp) per 100g of discard keeps the acidity mild without leaving a soapy aftertaste, which makes 1.1g the right dose for 225 g of discard in rosemary olive oil discard crackers.
