How Two-Stage Pre-ferment Deduction & Micro-Unit Approximations Work
In Baker's Math, Total Flour = 100%. When you ferment 30% of your flour in Stage 1 at 100% hydration, Stage 1 uses A = Total_Flour × 0.30 of flour and C = A × 1.00 of water.
In Stage 2 (Tomorrow), we deduct both from your main mixing bowl: B = Total_Flour − A and D = Total_Water − C. Because (C + D) / (A + B) = 65.0%, changing your poolish, biga, or sourdough percentage never distorts your final dough hydration.
Micro-ingredient tsp approximations: Kitchen teaspoons vary by grind and packing density. We display volume approximations alongside exact gram weights using standard culinary benchmarks: 1 tsp fine salt ≈ 6.0 g, 1 tsp instant dry yeast ≈ 3.2 g, 1 tsp granulated sugar ≈ 4.2 g, and 1 tsp honey ≈ 7.0 g.

For 6 × 260g balls = 1,560g net × 1.02 (+2.0% waste buffer) = 1,591g scaled

| Stage / Ingredient | Baker's % | Weight (g) | Approx. Volume (tsp) |
|---|---|---|---|
| Stage 1 (Poolish) · Flour (A) | 30.0% | 280.5 g | Weigh on scale |
| Stage 1 (Poolish) · Water (C) | 30.0% | 280.5 g | At 100% hydr. |
| Stage 1 · Instant Dry Yeast (0.1% of A) | 0.03% | 0.28 g | ≈ 0.09 tsp (1 tsp ≈ 3.2g) |
| Stage 2 Main Dough · Remaining Flour (B) | 70.0% | 654.4 g | Total flour = 934.9 g |
| Stage 2 Main Dough · Remaining Water (D) | 35.0% | 327.2 g | Total water = 607.7 g |
| Stage 2 · Fine Sea Salt | 2.50% | 23.4 g | ≈ 3.90 tsp (1 tsp ≈ 6g) |
| Stage 2 · Olive Oil / Fat | 1.50% | 14.0 g | Liquid fat |
| Stage 2 · Sugar / Diastatic Malt | 0.50% | 4.7 g | ≈ 1.11 tsp (1 tsp ≈ 4.2g) |
| Stage 2 · Honey | 0.50% | 4.7 g | ≈ 0.67 tsp (1 tsp ≈ 7g) |
| Stage 2 · Remaining Instant Dry Yeast | 0.17% | 1.59 g | ≈ 0.50 tsp (1 tsp ≈ 3.2g) |
| Total dough (×1.02 buffer) | 170.2% | 1,591.2 g | Net: 1,560 g |
What people hate about the other tools
We read the reviews of the incumbents before writing this page. Every complaint below maps to a decision in the tool above.
My understanding of poolish (having watched Vito's video I admit it was abit confusing to understand %poolish). Anyway this is how I work out poolish.
In this toolAuto-deducts preferment flour and water into clear Stage 1 (Poolish/Biga/Levain) and Stage 2 mixing cards.Also PizzApp doesn't have an option for honey. Do I need honey for a poolish using instant dry yeast?
In this toolIncludes dedicated slots for honey, diastatic malt, oil, and custom multi-flour blends locked to 100%.I always use for 70% hydration and 4 * 260g dough balls (there's a lot of waste so the real size will usually be around 245g)
In this toolAdds a one-click 0%–5% bowl waste compensation toggle so final portioned dough balls hit exact target weight.
