blanchera

Blanchera is a term originating from the culinary world, referring to a cooking technique that involves briefly immersing food in boiling water, followed by an immediate plunge into ice-cold water. This process is known as shocking or refreshing the food. The primary purpose of blanching is to halt the cooking process, preserve the food's color, texture, and nutrients.

When vegetables are blanched, enzymes that cause them to soften and lose their vibrant hues are deactivated. This is particularly useful when preparing vegetables for freezing, as it helps maintain their quality over time. Blanching can also be used to loosen the skins of certain fruits and vegetables, such as tomatoes or almonds, making them easier to peel.

In the context of meats and poultry, blanching can serve to remove impurities, excess fat, or a strong odor. For instance, blanching bones before making stock can result in a clearer, cleaner-tasting broth. The quick dip in boiling water also helps to set the surface of the food, which can be beneficial in certain preparations.

The duration of blanching varies depending on the type and size of the food item. Delicate greens might only require seconds in boiling water, while tougher root vegetables may need a few minutes. The subsequent ice bath is crucial for rapidly cooling the food and stopping the enzymatic action initiated by the heat. Blanching is a simple yet effective technique used across various cuisines for food preparation and preservation.
