Mozzarella Recipe

Prepare equipment

Sanitize a large stainless-steel pot (at least 3–4 L capacity), a long knife or curd cutter, a slotted spoon, a thermometer, a 2-cup measure, a colander lined with cheesecloth or a fine sieve, and a microwave-safe bowl (or a saucepan for hot-water stretching).

Pour 2 liters of whole milk into the sanitized pot. Gently heat the milk over low-medium heat, stirring occasionally to prevent scorching, until it reaches 32°C (90°F). Use the thermometer to monitor temperature accurately.

When milk is at 32°C (90°F), sprinkle 1 teaspoon mesophilic starter evenly over the surface. Let sit undisturbed for 1 minute to rehydrate, then gently stir it into the milk with an up-and-down motion for about 1 minute to distribute evenly.

Dilute 1 teaspoon liquid rennet in 50 ml of cool, chloride-free water. Pour the diluted rennet into the milk and stir gently for 20–30 seconds with an up-and-down motion. Stop stirring and cover the pot. Let the milk sit undisturbed for 30–45 minutes at ambient temperature until it forms a clean break curd (a firm custard-like set).

After the curd has set, check for a clean break: insert a knife at an angle, lift a bit of curd, and the split should show clear whey. If set, cut the curd into 1–1.5 cm (3/8–1/2-inch) cubes with a long knife, making parallel cuts one way and then the other to form a grid.

Gently stir the curds for 5 minutes to help them firm and expel whey. Then slowly heat the curds to 38–40°C (100–104°F) over 10–15 minutes, raising temperature by about 1°C every 1–2 minutes while stirring gently and occasionally to prevent matting. Maintain even heat; once at target, stir for another 5 minutes.

Allow curds to settle for 5 minutes. Using a slotted spoon, transfer curds into the colander lined with cheesecloth to drain whey. Reserve the whey in the pot — you may use some hot whey for stretching if not using a microwave. Let curds drain for 5–10 minutes until they hold together but are still moist.

Test a small piece of curd for stretchability: pinch off a golf-ball–sized piece, press or knead it to expel whey and form a flat disk. Microwave method: place the curd piece in a microwave-safe bowl and heat on high for 20–30 seconds, then fold and knead with a spoon or gloved hands to distribute heat. If not pliable, return to the microwave in 10–15 second bursts until the curd becomes shiny and stretches like taffy. Alternatively, if using hot whey, submerge the curd in hot (approximately 75–80°C/167–176°F) whey until it softens and becomes elastic, then stretch by hand or with a spoon.

When the curd is hot and pliable, stretch and fold repeatedly: pull the curd into a rope, fold it back on itself, and repeat. This aligns the proteins and creates the characteristic mozzarella texture. Work quickly while warm. If the curd tears instead of stretches, reheat briefly.

Once the curd is smooth and shiny, flatten it, sprinkle 1.5 tablespoons non-iodized salt over the surface, and knead/fold to distribute the salt evenly. Taste and adjust lightly if desired.

Form mozzarella into balls: divide the mass into 6 equal pieces (about 115–125 g each for 2 liters milk), shape each into a smooth ball by tucking edges underneath and rolling between palms.

Prepare an ice bath: combine 500 ml cool chloride-free water and ice cubes (about 2 cups) in a bowl. Immediately transfer the mozzarella balls into the ice bath to cool quickly for 5–10 minutes; this firms the shape and stops stretching.

Store finished mozzarella balls submerged in lightly salted water (dissolve 1/2 tsp salt in 250 ml water) in an airtight container in the refrigerator for up to 3–5 days. For immediate use, serve at room temperature for best flavor and texture.
