Molleja

Molleja, also known as sweetbread, refers to the thymus (corazón or heart) and pancreas (cuello or neck) of beef cattle, with the former being smoother, less fatty, and more flavorful compared to the latter. Molleja is typically prepared one of two ways.

It is either soaked overnight in water or milk, then boiled and grilled, or only grilled twice, first to precook and then to form a crispy outside. When perfectly prepared, the texture of molleja is crunchy on the outside and buttery on the inside.
