The harder the vegetable the longer it needs to blanch - root vegetables need 4 minutes to boil, while very soft vegetables only need about 1 minute.
After you are finished blanching, wash the vegetables in ice-cold water and dry them well.
After they cool off, put the vegetables in special containers or bags. You need to put them in the freezer as soon as possible.
Vegetables that are used for salads and desserts aren’t the only types of vegetables we can freeze.
Most of the vegetables can be kept in a freezer for up to 12 months. Anything longer than that won’t make it inedible, but will make it lose its quality.
