If you have never tried this cheese before, Burrata is worth finding. Les Amis du Fromage receives it in fresh every Thursday and its a cheese that needs to be consumed within a day of purchase. Burrata has a very short shelf life and is at its best when enjoyed fresh.
According to Wikipedia:
Burrata is a fresh Italian cheese, made from mozzarella and cream. The outer shell is solid mozzarella while the inside contains both mozzarella and cream, giving it an unusual, soft texture. It is also defined by some sources as an outer shell of mozzarella filled with butter or a mixture of butter and sugar. It is usually served fresh, at room temperature. The name “burrata” means “buttered” in Italian.
