It’s burrata:

Burrata is a fresh Italian cheese with a thin mozzarella shell and a soft, creamy center made of pulled curds (stracciatella) mixed with cream.[1]

Originating in Puglia (southern Italy), burrata is traditionally formed by making a pouch of stretched-curd (pasta filata) mozzarella, filling it with stracciatella and cream, then sealing it so the inside stays luxuriously soft and oozing when cut.[2][3]

Taste and texture: Burrata is mild, slightly sweet, and buttery in mouthfeel; the contrast between the chewy outer shell and the silky, creamy interior is its defining feature.[4][5]

How to eat it: Serve burrata fresh at room temperature with simple pairings — ripe tomatoes, olive oil, crusty bread, prosciutto, or salads — to highlight its creamy center; cut it open at the table to enjoy the visual and textural effect.[6][4]

Storage and notes: Burrata is a very fresh cheese best eaten within a day or two of production and should be kept refrigerated until shortly before serving.[7][8]
