Recommendations of experienced housewives

How to keep onions for the winter and can they be frozen

When freezing onions, remember that for the first few weeks they will smell quite strong. There is a risk that it will saturate the rest of the food. Therefore, experienced housewives advise putting onions in the freeze in a separate empty box in the freezer. When the product freezes well, other vegetables will "take root" next to it.

It is worth refusing to re-freeze and get exactly as much onion as you plan to spend at a time... As a result of contact with air, taste is lost, and repeated freezing becomes meaningless.

Some housewives cut onions for freezing and first put them in one layer in a deep plate or tray, cover them with cling film and send them to the freezer for several hours. And then they take it out and pour it into special bags for storage. Thus, the vegetable freezes faster and better.


The opinion that onions should not be frozen is wrong. Both bulbs and greens perfectly tolerate low temperatures and, when following simple recommendations, fully retain their beneficial properties.
