Description
High-heat searing on a thick metal plate creates complex Maillard reactions while preserving juiciness.
Technical
The thermal mass of the chapa (3-5cm thick steel) provides even heat distribution, allowing simultaneous conduction and radiant heat transfer. This creates a temperature gradient from 180-220°C at the surface, enabling rapid protein denaturation (60-65°C for myoglobin) while maintaining internal moisture.
Culinary Significance
Produces meats with a crisp crust and tender interior, ideal for thin cuts like entraña (skirt steak) and achuras (offal). The flat surface allows cooking of small items like provoleta cheese without losing them through grill grates.
