How to Use 60g (0.25 Cups) Sourdough Discard in Soft Discard Pullman Sandwich Loaf
Got a small 60g jar remnant? Exact flour and liquid deductions to fold 60g of unfed discard into soft discard pullman sandwich loaf for tender flavor.
Scale the soft discard pullman sandwich loaf formula once and you are done: 500g flour minus the 30g inside your 60g of discard is 470g, and 320g of milk & water minus the 30g it contains is 290g. Add 0.3g of baking soda and cook at 375°F (190°C) for 35–40 min.

Soft Discard Pullman Sandwich Loaf Conversion Grid: 60g Discard Against Neighbouring Doses
Neighbouring discard weights around 60g, useful when your jar remnant is larger or smaller than planned.
| Starter Water Ratio | Hidden Flour | Hidden Water | Flour to Weigh | Liquid to Weigh | Soda to Add |
|---|---|---|---|---|---|
| 100% starter, 60g serving [Primary] | minus 30g flour | minus 30g liquid | 470g flour left | 290g liquid left | 0.3g NaHCO3 |
| 50% starter, 70g serving Leaner Dough | minus 46.7g flour | minus 23.3g liquid | 453.3g flour left | 296.7g liquid left | 0.4g NaHCO3 |
| 75% starter, 50g serving Wetter Dough | minus 28.6g flour | minus 21.4g liquid | 471.4g flour left | 298.6g liquid left | 0.3g NaHCO3 |
| 125% starter, 80g serving Tight Dough | minus 35.6g flour | minus 44.4g liquid | 464.4g flour left | 275.6g liquid left | 0.4g NaHCO3 |
| 100% starter, 40g serving Loose Dough | minus 20g flour | minus 20g liquid | 480g flour left | 300g liquid left | 0.2g NaHCO3 |

Why Even a Small 60g Sourdough Discard Addition Tenderizes Soft Discard Pullman Sandwich Loaf
A 60g discard addition shifts the flour-to-liquid ratio of soft discard pullman sandwich loaf by more than the numbers suggest, because the discard's water is already partially bound by fermented starch. The practical consequence is that the 290g of milk & water you add behaves differently from a cold, free liquid, and the batter will feel tighter than the arithmetic suggests.
Temperature changes how fast that neutralisation runs. At 75°F (24°C) the 0.3g of bicarbonate reaches the 1g of acid quickly, but in a cold kitchen the reaction stalls and the soft discard pullman sandwich loaf batter can taste sour even though the maths was right.
How to Mix Soft Discard Pullman Sandwich Loaf with 60g Sourdough Discard
- Pre-weigh for Accuracy: Set out 60g of discard, 470g of flour and 290g of milk & water on the scale before you begin — discard sticks to spoons and misreads badly.
- Blend the Discard Smoothly: Work 60g of discard into the 290g of liquid with a whisk until the mixture is completely uniform, with no visible fermented lumps.
- Fold in Flour & 0.3g Soda: Add the 470g of sifted flour and the bicarbonate, then mix only until no dry patches survive.
- Cook to Spec (375°F (190°C) for 35–40 min): The soft discard pullman sandwich loaf is ready when the centre springs back and the surface is no longer wet.
Common Scaling & Troubleshooting Questions (-30g)
Will 60g of discard make soft discard pullman sandwich loaf taste sour?
Only if the acid is left un-neutralised. The 0.3g of bicarbonate reacts with the roughly 1g of acid inside 60g of discard, converting it to mild sodium salts and leaving a pleasant background tang.
Does 60g of discard leaven soft discard pullman sandwich loaf on its own?
Unfed fridge discard adds tang and tenderness to soft discard pullman sandwich loaf, while the recipe's baking powder, the 0.3g of baking soda, or commercial yeast provides the primary rapid leavening at 375°F (190°C) for 35–40 min.
What happens if I add 60g 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 0.3g of bicarbonate or a full measure of baking powder to get the rise at 375°F (190°C) for 35–40 min.
