How to Peel Tomato - as part of the expert series by GeoBeats. One of the great tips that I love to teach when I teach cooking classes is how to peel a tomato. Many recipes call for peeled tomatoes. For instance, every tomato sauce will ask you to peel a tomato. Traditionally, the way you peel a tomato is, you plunge it into boiling water for about an minute and it loosens the skin. But there is an easier way, especially if your recipe asks you to do a tomato in such a way that it is going to end up all saucy and mushy anyway. Not hunks, let's say. And that is by taking the tomato. You have got your sharp knife, cutting it in half, squeezing out the seeds with just a shake. The seeds come out. And now what you do is, you are going to use the skin of the tomato to protect your hand and take a standing box grater, using the large holes. And you are going to grate the tomato. You can see my hand is being protected by the skin. All the flesh of the tomato is now in the bowl. It is a lot better than plunging it into boiling water, which involves a number of steps. Here, you have got your tomato sauce in just a few swipes of your hand.
