Burrata is a fresh, un-aged cow cheese imported directly from Italy. It has a semi-liquid filling inside a shell of mozzarella which is wrapped in leaves. This cheese's soft, loose texture and its creamy flavor make it popular enough that many specialty stores stock burrata, despite the extra hassle involved in importing and storing it. Because it is made to be eaten young, only buy burrata if you can eat it within a couple of days. During those days, proper storage is important.
Purchase the freshest burrata cheese possible. If the burrata cheese you buy is already several days old, do not store it -- eat it immediately.
Wrap the burrata cheese gently in plastic wrap, making sure that it is completely covered in the plastic wrap and that there are no holes or gaps where air can get in.
Place the burrata cheese into the refrigerator. If you have a refrigerator that tends to get too cold or freeze in certain areas, such as against the back or at the very top, store the burrata cheese away from these parts.
Keep the burrata cheese in the refrigerator for two to three days. If you notice the leaves wrapping the burrata start to wither or turn brown, eat it immediately; by the time these leaves begin to show their age, the burrata is near the end of its lifespan.
Take the burrata out of the refrigerator and allow it to warm to room temperature before serving or eating it.
