A pouch of fresh mozzarella filled with stracciatella — shreds of curd soaked in cream — from Puglia: milky, sweet, and best within a day or two of making.
Italian delis, as fresh as possible — check the date and buy it the day you'll eat it.
Worth knowing
Take it out of the fridge 30–60 minutes before serving; cold, it tastes of very little. Season the inside with flaky salt and good oil, and put it next to something sharp or salty — acid fruit, anchovy, cured ham.
