Prepare the biga
5 hBloom yeast (1.5g) in warm water (~100°F / 38°C) for 10 minutes. Then mix tipo 00 flour (300g), bread flour (180g), and bloomed yeast water. Add water (216g) (at 45% hydration) and mix until a smooth, firm dough forms. Shape into a ball, place in a lightly oiled container, and let ferment at room temperature for 5 hours.
- Use a mixer with reverse function if available for preferments.
- Ensure the biga is mixed until cohesive but firm.
- Cover well to avoid drying during room temp fermentation.
