Cover the tomatoes with boiling water. Leave in the water for a couple of minutes until you see the skin start to soften. Next plunge them into cold water – you can even add ice cubes to the water to make sure it’s really cold. When the tomatoes cool down quickly it means the skin will peel off easily. After a minute or so you can start to peel off the skins. Use a knife if you find this easier. Using a gas flame If you only have one tomato to skin, it may be easier to try this method: Poke a fork into the tomato and make a criss-cross slit in the top of it. Then hold it in the top part of a gas flame (you can just use your hob). Once the skin looks quite charcoaled and blackened use a knife to peel the skin away.
