Why it Works: Best Practices for Bread Crumbs
One of the best ways to season a food is to remove its natural liquid and replace it with a more flavorful one. The same concept holds for bread crumbs. Bread can best absorb butter and spices when dried. In a pinch, bread can be cut into slices and placed in a warm oven to dry. However, this method toasts the bread without removing most of the liquid. A better way is to slice the bread and let it sit, uncovered, overnight. This drying method allows the starch to release its water (heating causes starch to hold more water).
