There’s lots of goodness in the skin of fruits and vegetables, but some recipes call for taking the skin off and that can be fiddly with peaches and tomatoes. This time-honoured trick will do the job easily: blanch your fruit in boiling water, then dunk it in iced water and peel the skin right off with your fingers.
Saveur Magazine has a great tutorial on the technique. Boil some water and make a small cross cut in the base of the peaches or tomatoes before dropping them gently in. Take the fruit out after a couple of minutes and drop it immediately into a bowl full of iced water. The water stops the cooking process, and when the fruit is cool enough to touch, you can pull the skin right off. You can use a knife (as seen in the video above), but in many cases you’ll be able to peel the fruit simply with your fingers.
