Ladle the curds gently into the cloth without breaking them up. Let drain for 5 minutes for a soft, spreadable ricotta. Let drain for 20 to 30 minutes for a firmer, drier :INFO Why Ultra-Pasteurized Milk Fails Ultra-pasteurized milk is heated to around 138 Celsius for a short time during processing. This breaks down the calcium structure that normal pasteurization leaves intact. When you add acid to UHT milk, the protein cannot coagulate properly and you get a thin, grainy slurry instead of distinct curds. Look for the freshest standard pasteurized whole milk you can find, ideally from a local dairy. :NOTE Variations Worth Trying Adding a splash of heavy cream to the milk produces an extra rich ricotta sometimes called "doppio crema" style. Using goat milk instead of cow milk gives a slightly tangier, brighter result with smaller, finer curds. For a lemon-forward flavor, use lemon juice as your acid and add a little lemon zest after draining. This version is excellent on toast with honey. :QUOTE [quotetype:personal] Fresh ricotta made at home tastes like proof that some things just should not come from a plastic tub.
