Description
Controlled steam environment maximizes oven spring and crust formation through delayed surface drying.
Technical
The Dutch oven's sealed environment traps evaporating water from dough, maintaining 100% relative humidity during initial bake. This prevents premature crust formation, allowing maximal starch gelatinization (60-70°C) and gluten coagulation (70-80°C) before Maillard reactions (110°C+) commence.
Culinary Significance
Essential for achieving professional-quality sourdough with glossy, blistered crusts and open crumb without commercial steam injection ovens.
