👉 The term "castellet" is a French word that refers to a type of cheese made from sheep's milk. It is made by first removing the skin and yolks from the cow's milk, then adding salt and rye flour to form a dough, which is then pressed into a mold and allowed to cure for several days before being baked. The finished product is then served with a variety of toppings such as cheese, herbs, or fruit.
