What technique is used to remove the skin from tomatoes?

The technique that is primarily used to remove the skin from tomatoes is blanching. This method involves briefly immersing the tomatoes in boiling water for a short period and then transferring them quickly into an ice bath. This process helps to loosen the skin, making it easy to peel away without damaging the flesh of the fruit.

Blanching tomatoes is especially useful because it preserves their flavor and texture compared to other methods. The rapid heating and cooling cause the skin to separate from the flesh without cooking the tomato itself, allowing for a clean, effective way to prepare tomatoes for sauces, salsas, or other dishes where skin removal is desirable.
