Overview

Mozzarella is a fresh, unaged cheese made by the pasta filata (stretched-curd) method, traditionally from Italian Mediterranean buffalo milk. It has a soft, elastic texture, a mild milky flavor, and a clean, slightly tangy finish. Fresh mozzarella is white to pale yellow depending on the animal’s diet and is best consumed within days of production.

Origin and history

Mozzarella originated in southern Italy, specifically in the regions of Campania, Lazio, Apulia, and Molise, where water buffalo were introduced in the early Middle Ages. The first documented reference to mozzarella appears in a 12th-century text from the monastery of San Lorenzo in Capua, describing a cheese made from buffalo milk [2]. The pasta filata technique, which involves kneading and stretching hot curd in whey or water, was developed as a preservation method that also produced a uniquely pliable cheese. Mozzarella di Bufala Campana received Protected Designation of Origin (PDO) status in 1996, restricting the name to cheese made from Italian buffalo milk in specified provinces. Cow’s-milk versions, often labeled fior di latte, became widespread in the 20th century as production scaled for pizza and export markets.

Varieties and aliases

  • Mozzarella di Bufala Campana (PDO, buffalo milk)
  • Fior di latte (cow’s milk mozzarella)
  • Mozzarella affumicata (smoked mozzarella)
  • Bocconcini (small balls, about 1.5 inches)
  • Ciliegine (cherry-sized balls)
  • Ovoline (egg-sized balls)
  • Treccia (braided mozzarella)
  • Burrata (mozzarella shell filled with stracciatella and cream, a related pasta filata cheese)
  • Low-moisture mozzarella (aged or dried, used for pizza and cooking)

Culinary uses

Fresh mozzarella is most commonly served uncooked in Caprese salad (with tomatoes, basil, olive oil, and salt) or as a table cheese with bread and cured meats. Low-moisture mozzarella is the standard pizza cheese, valued for its melt, stretch, and browning properties. It is also used in baked pasta dishes such as lasagna, eggplant Parmesan, and stuffed shells. In Italian-American cooking, mozzarella is often fried as mozzarella sticks or used in sandwiches like the chicken Parmesan sub.

Cross-cuisine context

Mozzarella has close analogues in several cuisines represented on the Yum platform. The Filipino fresh cheese kesong puti, traditionally made from carabao (water buffalo) milk curdled with vinegar or citrus, is the closest direct analogue in texture and use [3]. Georgian sulguni is a brined pasta filata cheese similar to mozzarella but tangier and saltier, used in khachapuri Adjaruli and served smoked or fried. Guatemalan queso de capas is a layered pulled-curd cheese with mozzarella-like melt properties. Salvadoran quesillo, a fresh stretched-curd cheese, is the canonical cheese for pupusas and is described as similar to a wetter mozzarella. Armenian chechil is a hand-pulled string cheese eaten with lavash and herbs, though it is aged and saltier than fresh mozzarella. Korean cuisine uses low-moisture mozzarella as a topping for cheese-tteokbokki, Korean corn dogs, and buldak, where it functions as a mild, stretchy counterpoint to spicy sauces.

Notes for cooks

  • Fresh mozzarella should be stored in its whey or brine and used within a few days. It does not freeze well; freezing destroys the delicate curd structure.
  • Low-moisture mozzarella is the correct choice for pizza, lasagna, and any application requiring even melt without water release. Fresh mozzarella will release whey when baked, potentially making crusts or sauces watery.
  • Signal characteristics of fresh mozzarella: a springy, non-rubbery texture; a clean milky aroma; and a surface that is moist but not slimy. Yellowing or sour smell indicates age.
