From Cakes to Casseroles: The Magic of Sour Cream in the Kitchen

The condiment we know as sour cream, originated from the process of adding lactic acid bacteria to regular cream with at least 18% milk-fat.

This process is commonly known as souringtherefore the name, sour cream.

The two most common types of bacteria used in the production of sour cream are:

  • Lactobacillus delbrueckii subsp. bulgaricus: A bacteria that ferments lactose – the sugar found in milk – into lactic acid, creating that characteristic sour taste.
  • Streptococcus thermophilus: A bacteria that supports the development of acidity and texture, contributing to the overall creaminess of the sour cream.

The balance of these two bacterias are essential, as they not only affect the flavor and texture but also the nutritional profile of the final product.

The beauty of sour cream lies in this harmonious fermentation process, which elevates both taste and versatility in using it to cook and bake.

Acidified sour cream is soured and thickened by the direct addition of an acid, such as vinegar, instead of a fermentation process.
