Ricotta is a soft, creamy, and slightly grainy Italian cheese made from whey leftover from the production of other cheeses. It has a mild, slightly sweet flavor with a delicate texture that makes it versatile for both sweet and savory dishes. Ricotta is commonly used in Italian cuisine for dishes such as lasagna, cannoli, and ravioli, as well as in desserts like cheesecake and tiramisu. It is a popular ingredient in many recipes due to its ability to add richness and creaminess without overpowering other flavors.
