Can you freeze opened ricotta cheese to extend its shelf life?
Yes, you can freeze opened ricotta cheese to extend its shelf life. Freezing will help to slow down the growth of bacteria and mold, allowing you to store the cheese for several months. When freezing ricotta cheese, it’s essential to use an airtight container or freezer bag to prevent freezer burn and other flavors from affecting the cheese.
Before freezing, make sure to press out as much air as possible from the container or bag to prevent the formation of ice crystals, which can affect the texture of the cheese.
