Fermentation is useful in cooking primarily for preserving food and altering its properties, creating unique flavors and textures.
Fermentation, at its core, involves using microbes to create food or change its existing properties. This process has several useful applications in cooking:
-
Preservation: A primary use of fermentation is to preserve food. According to research, many cultures began fermenting foods to preserve them. Fermenting vegetables, for instance, allowed people in harsh winter climates to consume them year-round.
-
Flavor Development: Fermentation introduces distinct flavors to foods. Think of the tangy taste of sauerkraut or the umami richness of miso. These flavors are created by the metabolic activity of the microbes during fermentation.
-
Texture Modification: The process can also alter the texture of food. Fermenting milk, for example, can result in yogurt, with its thickened and creamy consistency.
In summary, fermentation enhances cooking through preservation, flavor creation, and textural changes in food.
