Spray the tomatoes with vinegar and then rinse to get rid of impurities and pesticides. Place them in a bowl.
Use a paring knife or sharp knife to score an X on the bottom of each tomato. Do not cut the tomato too deep - just enough to pierce the skin. Make the X not too deep into the flesh. Place them back into the bowl until the next set.
Bring a pot filled with water, enough to submerge the tomato.
With a slotted spoon, carefully place the tomato inside the pan with boiling water. Let it sit for 30 seconds or longer but not more than 1 minute.
With the slotted spoon or regular spoon (wooden or metal), remove the tomato from the boiling water and immediately plunge into ice-cold water to prevent it from cooking longer.
Where the x is located, the skin should have started to peel off. Peel off the skin, and you may also use the knife to remove the skin gently.
Use in your favorite recipes and when a recipe calls for it.
