Easy enough to make at home.. Stick a fork in one end of a ripe tomato
and slowly rotate it over the flame of a gas stove. When the skin
shrinks enough so it's wrinkled and cracked and starting to char , wrap
it in a damp cloth and let it sit for a while to steam and cool. Then
peel it. I often do this under a running faucet. Works with peppers
too..
