Blanching is a cooking method where food is immersed in boiling water for a short time, then immersed into iced water to stop the cooking. It is used on vegetables, meat, bones for stock, fruits etc. Here I have explained how to blanch vegetables, starting with onions. I will include other food ingredients soon.


  • Blanching is used to brighten and enhance the natural colour of vegetables e.g green beans, cauliflower, onions, carrot, broccoli, etc.
  • To soften vegetables for use as part of an uncooked dish e.g. salad
  • To loosen the skin of some vegetables and nuts for easy peeling e.g tomatoes, almonds
  • To help extend the lifespan of stored vegetables in the fridge.
  • To mellow or remove the taste of strong tasting vegetables e.g cabbage, onions

Place a pot of water over medium-high flame. The water should be enough to cover the tomatoes well. 


Into a large bowl, pour very cold water, if you can, add ice cubes, set aside. 

Bring the water in the pot to a rolling boil. Place tomatoes into the boiling water. Do not over-crowd the water. Leave to boil for 1-2 minutes depending on how thick the tomato skin is. The skin will start splitting.
