Freezing slows down
decomposition, but doesn't stop it. To keep vegetables frozen longer, without degrading the quality, you need to briefly
boil the vegetables. This is called blanching, and is done by bringing water to a boil, adding the vegetables, and letting them boil for several minutes. The vegetables should be immersed in cold water at the end of the blanching period. The amount of time each vegetable is blanched for depends both on the vegetable, and the size pieces it has been cut into.
