Pearson Square Strength Calculator, Commercial Flour Specs & Dynamic Master Recipes
In professional pizzerias, millers and pizzaioli blend flours using the mathematical Pearson Square Method to reinforce weak supermarket flours, hit precise fermentation targets (e.g. W 280), or introduce flavorful whole grains without sacrificing structural gas retention.
The final strength represents a weighted linear mass balance:
Calculate exact mass ratios and weights to blend any two flours into your target strength.
To help you accurately input W values and characteristics into the Blending Engine, here is the technical specification breakdown of the most widely used pizza flours:
The global gold standard for traditional AVPN Neapolitan pizza. Engineered for 12–24h ambient fermentation and wood/gas ovens at 850°F–900°F.
Stronger protein structure for 24–48h cold fermentation or higher hydration (65%–70%). Excellent resilience in home countertop pizza ovens.
Engineered specifically for Canotto style and 100% Biga preferments. Absorbs 75%–80%+ hydration with massive honeycomb alveolar expansion.
The undisputed champion for 500°F–550°F home kitchen ovens on a baking steel. Malted barley flour delivers golden crust browning and chewy crumb.
Milled from American soft and hard wheat to fine 00 specifications. Unmalted for clean performance in Ooni, Gozney, and Breville high-heat ovens.
Proprietary deglutenized wheat starch and plant fibers that stretch, brown, and chew remarkably close to authentic gluten dough without allergens.
Three laboratory-tested, scientifically balanced master formulas engineered for specific flours, fermentation kinetics, and baking environments.
Oven: 850°F–900°F (450°C–500°C) · Flour: Tipo 00 W 260–280 · Hydration: 62% · Direct 24h Ambient
| Ingredient | Baker's % | Scaled Weight (4 balls @ 280g) |
|---|---|---|
| Tipo 00 Flour (W 260–280) | 100.0% | 679 g |
| Water (68°F / 20°C) | 62.0% | 421 g |
| Fine Sea Salt | 2.8% | 19.0 g |
| Instant Dry Yeast (IDY) | 0.04% | 0.27 g (Fresh: 0.8g) |
Method: Dissolve salt in water, whisk in yeast, incorporate 100% flour gradually. Knead 10–12 min (final temp 23°C). 2h bulk rest at room temp, portion into balls, proof 20–22h at 68°F–72°F. Bake 60–90s at 485°C.
Oven: 800°F–850°F (430°C–460°C) · Flour: Tipo 0/00 W 340–380 · Total Hydration: 75% · 18h Biga + 48h Cold
| Phase / Ingredient | Baker's % | Scaled Weight (4 balls @ 280g) |
|---|---|---|
| Phase 1: 100% Biga Preferment | ||
| Strong Flour (W 340–380, e.g. Nuvola Super) | 100.0% | 628 g |
| Biga Water (60°F / 16°C) | 45.0% | 283 g |
| Instant Dry Yeast (IDY) | 0.35% | 2.2 g (Fresh: 6.3g) |
| Phase 2: Final Bassinage Closure | ||
| Ice Water (Chilled to 38°F / 3°C, added gradually) | 30.0% | 188 g |
| Fine Sea Salt | 2.8% | 17.6 g |
| Diastatic Malt or Honey (Optional) | 0.5% | 3.1 g |
Method: Shred Biga coarsely (do not knead); ferment 18h at 16°C–18°C. Transfer cold Biga to mixer, add Phase 2 ice water in gradual bassinage splashes until silky (75% hydration). Bulk cold retard at 4°C for 48h. Ball and proof 5–6h before baking.
Oven: 500°F–550°F (260°C–290°C) on Steel · Flour: US Malted Bread Flour · Hydration: 65% + 2.5% Oil · 48–72h Cold
| Ingredient | Baker's % | Scaled Weight (4 balls @ 280g) |
|---|---|---|
| Malted Bread Flour (King Arthur Bread) | 100.0% | 654 g |
| Cold Water (40°F / 4°C) | 65.0% | 425 g |
| Extra Virgin Olive Oil | 2.5% | 16.4 g |
| Fine Sea Salt | 2.5% | 16.4 g |
| Instant Dry Yeast (IDY) | 0.35% | 2.3 g |
| Diastatic Malt Powder / Sugar | 1.0% | 6.5 g |
Method: Autolyse flour, water, and malt for 20 min. Add yeast, salt, and olive oil; knead 8 min. Cold retard at 38°F–40°F for 48–72h. Portion into balls 3h before baking. Preheat Baking Steel at 550°F for 60 min. Switch to broil and bake 4–5 min.
