The small amount of effort it takes is worth the glorious taste of peel-free tomatoes! Although peeling a tomato is not an extremely common method in many home kitchens, it is a very useful process to be familiar with. Some recipes will call for a tomato to be peeled and seeded in order to rid the tomato of any bitter taste that the peel and seeds can contain. This method can also be used for peeling peaches and plums. To remove the skin of tomatoes, place them in warm water for about 5-10 minutes. The skin can then be peeled off easily. In case of over ripe tomatoes, just place them in cold water and add some salt. They will become firm and fresh overnight.
