- Ice water
Set a large pot of water on the stove to boil while you prepare the tomatoes.
Turn tomatoes over to the bottom and, using a paring knife, cut a shallow X in the bottom. Core tomatoes, if you like.
Carefully lower tomatoes into the boiling water, in batches. Remove after about 30 seconds, once skins start to crack.
Immediately put tomatoes into the bowl of ice water.
Once tomatoes are cool enough to handle, peel skins from tomatoes and use in your favorite recipe.
