Ricotta

Ingredients

• 2 l whey
• 500 ml milk
• 10 g table salt
• 6 g citric acid
• 130 ml lemon juice

Method

Ricotta is built on acid-in-cooking, not heat alone. The acid denatures the milk proteins at a precise temperature window, forcing them to coagulate and separate from the liquid whey. This is why you need both the acidic medium and aggressive heat — neither works without the other.

Combine the whey and milk in a heavy-bottomed pot. Whey alone is lean; the added milk boosts fat content and gives you a richer final texture. Add salt and stir to distribute evenly. Bring the mixture to 80°C over medium heat, stirring occasionally to ensure even warming. This preliminary stage matters: too fast and you'll overshoot; too slow and you'll cook off moisture you need. You're aiming for steady, gentle ascent.

Once the surface steams steadily at 80°C, add the citric acid and lemon juice all at once. Stir aggressively for 30 seconds — the acid shock will cause visible separation within moments. Small white flakes and curds will rise as the whey turns cloudy and faintly greenish. Now increase the heat to 90°C and hold it there for 5–8 minutes. The curds will swell and firm up; they'll start to feel granular rather than fleeting when you drag a spoon through them. This is the signal they're set properly and won't dissolve when you strain them.

Line a colander with fine cheesecloth — butter muslin works better than open-weave cloth; it catches finer particles. Pour the entire mixture through slowly and let gravity drain for 10–15 minutes. Don't squeeze or press; ricotta's texture comes from loose, delicate curd structure. A tight press makes it dense and grainy. Transfer to a clean container once the majority of whey has dripped through. The ricotta will be warm, pale, and soft enough to spoon. Use it warm, or chill it for up to five days in the fridge. If whey pools at the top during storage, drain it off before serving.
