Wo-homemade Mozzarella Logs Recipe

Prepare acids and rennet

Dissolve 1.5 tsp citric acid in 2 tablespoons cold water and set aside. Dilute 1/2 tsp liquid rennet in 2 tablespoons cool water and set aside.

Warm the milk and add citric acid

Pour 2 liters whole milk into a large heavy pot. Stir in the dissolved citric acid gently. Heat the milk over medium heat, stirring occasionally to prevent scorching, until it reaches 32°C (90°F). Use an instant‑read thermometer to monitor temperature.

Add rennet and form curd

Remove the pot from heat and gently stir in the diluted rennet for about 30 seconds. Stop stirring and cover the pot. Let the milk sit undisturbed for 5–10 minutes until it sets into a soft curd with a clean break when you insert a knife.

Cut and rest the curd

Using a long knife or curd cutter, cut the curd into 1–1.5 cm (3/8–1/2 inch) cubes. Let the cut curd rest undisturbed for 5 minutes to allow whey to expel.

Cook the curds

Gently heat the curds, stirring slowly, raising the temperature to 38–42°C (100–108°F) over 5–10 minutes. Maintain gentle stirring so curds stay separate but do not overwork them. Once at temperature, continue to stir gently for 2–3 minutes, then remove from heat.

Separate curds and whey

Using a slotted spoon or ladle, transfer curds into a colander lined with cheesecloth to drain off whey. Save about 1/2 cup of warm whey (or hot potable water) for stretching if needed. Let curds drain 5–10 minutes until they are firm but still moist.

Salt the curds

Transfer drained curds into a bowl and sprinkle 1.5 tsp salt evenly over them. Gently fold the curds to distribute the salt. Taste one small piece — it should be lightly seasoned.

Prepare hot liquid for stretching

Heat the reserved whey or clean water to about 80–85°C (175–185°F). You can microwave curds briefly instead: place a portion of curds in a microwave‑safe bowl and heat 20–30 seconds until very hot (but not boiling). Use caution—liquid will be hot.

Check elasticity

Using heat‑resistant gloves or a spoon, grab a handful of curd and test by pulling it. If it stretches like taffy and becomes glossy, it is ready to be stretched. If it crumbles, reheat in the hot water/whey for 10–20 seconds more and try again.

Stretch and fold

Stretch the curd by pulling and folding it back on itself repeatedly. Work quickly while it's hot; if it cools and becomes stiff, return to the hot water briefly. Continue until the curd is smooth, shiny and elastic (5–10 minutes).

Form logs

Shape the warmed, stretched cheese into logs (approx. 15–20 cm / 6–8 inches long) by rolling and rolling between your hands or on a clean surface. For uniform logs, fold and roll until surface is smooth and ends are tapered. Chill briefly (5–10 minutes) to set shape.

Optional brine

If you want a more evenly salted result, prepare a brine by dissolving 1 tbsp salt in 1 cup warm water. Submerge finished logs for 3–5 minutes, then remove and pat dry. Adjust brining time for salt preference.

Cool the logs quickly by placing them in an ice water bath for 5 minutes if you prefer firmer texture, or refrigerate uncovered on a tray for 30–60 minutes to finish setting. Store mozzarella logs in the refrigerator submerged in fresh, lightly salted water or wrapped in plastic for up to 5 days. For best texture, use within 2–3 days. Serve sliced as needed — warm and stringy when freshly made, milder and firmer after chilling.

Notes: Use whole milk not ultra‑pasteurized for proper curd formation. Temperatures are important: citric acid adjusts curd acidity; rennet sets the curd. If curds never form, check rennet potency or use fresher milk.
