Blanching the vegetables is indeed a very important factor. Many well-known chefs and cooking experts too stress on the fact of blanching the vegetables well. But, do you the reason why? Blanching vegetables happen to be the process that has been recommended as a pre-treatment before you freeze them. When you blanch the vegetables before freezing, they stay fresh for a longer time.

Without blanching, the vegetables tend to lose a part of their original color, texture, and taste after you freeze them. The main purpose of blanching is to counteract the changes in the vegetables by neutralizing their enzymes. It is due to this factor that the changes occur in vegetables. So, blanching indeed helps the vegetables to retain their quality after freezing. Although it is not necessary to do but surely in doing so, you get better results in the end.

There are three stages to the process of blanching. First is to pre-heat the water. Then you blanch the vegetables. And then you cool them. So, at first, put the water for blanching to boil. Then you put the vegetables inside the boiling water or can even steam it for a short while. And then finally you cool them quickly so that it does not get cooked. In the case of vegetables, the quickest and the most common method of blanching is just to put them in boiling water to blanch. This guide speaks about the exact process of doing so.

But you can also feel free to steam the vegetables if you wish. But the only thing is to make sure that you are steaming them for a longer duration. In the case of steaming the vegetables, you must keep them 2-3 times longer than you would normally keep them for blanching. Here you must also make a note of the fact that blanching is only done when you are freezing the vegetables raw.  In case if you are cooking or baking the vegetables before freezing, then, in that case, you must not blanch them.

The process to blanch vegetables before freezing

  1. Prepare the vegetables first, and make them ready for being used immediately after thawing.
  2. Put a pot of water in the oven to boil.
  3. As the water is being heated, make arrangements to give the vegetables an ice bath. Fill a large pot of water and put in it some ice cubes, if you are carrying it. Remember to avoid doing this process with ice cubes if it is only a handful of vegetables that you are blanching.
  4. As soon as the water in the pot starts to boil, put the prepared vegetables in the pot. Now put the lid over it and allow the water to boil again.
  5. When the water starts to boil one more time, set a timer and let the vegetables boil as per the time set on the timer. The timer that you have set for boiling the vegetables depends upon a number of factors. The type of vegetable you are blanching, its size, the cut, and also its texture as well. usually, it is about a minute for the leafy green vegetables. And for about 8-10 minutes if it is whole corn over the cob.
  6. As soon as you reach the time set on the timer, immediately put the vegetables for an ice bath in another container.
  7. Now allow the vegetables to swim in the cold water for about five minutes at least.
  8. Pick them up and dry them thoroughly. Although drying is not a process of blanching but, the vegetables must be completely dry before being put to freezing. Shaking the vegetables also brings out the water from them. It is indeed a useful technique. Now assemble all the blanched vegetables over a dishcloth. Let them dry for about thirty minutes. But before you move any further, get a paper towel and give the vegetables a gentle rum and dry them completely.  And thus, you are sorted.

Make sure to keep the ice bath cool or else you can pour ice water as well after being given them an ice bath.
