What You Need to Know
The earth’s thermal mass provides a stable, indirect heat source that promotes Maillard browning and caramelization of surface sugars. Collagen in proteins breaks down into gelatin, while starches gelatinize, resulting in tender, moist textures. The moist environment also encourages microbial activity that can affect flavor if not properly managed.
