avec fromage

Burrata is made similarly to mozzarella. During the production it’s streched to form a pouch that gets filled with soft mozzarella curd and the cream from the way. It is then knotted to keep the “surprise” inside, and when you eat it the texture and the taste make you think of a butter filling, hence the name.
