Sour Milk

Sour milk is milk that has naturally soured due to lactic acid fermentation. This process occurs when bacteria in the milk consume lactose and produce lactic acid, resulting in a thicker texture and tangy flavor. Its appearance can range from slightly thickened to curdled, depending on the extent of the fermentation. It's a versatile ingredient, especially valuable when fresh milk isn't readily available or when a distinct tangy flavor is desired. Explore cooking with sour milk as it can add moisture and a pleasant subtle sour taste to baked goods and other dishes.

Common Uses

  • Sour milk is often used in baking as a substitute for buttermilk, adding a tender crumb and slight tang to pancakes, waffles, and biscuits. It provides moisture and helps activate baking soda.
  • Use sour milk to tenderize meats. Marinating tough cuts of meat in sour milk helps break down muscle fibers, resulting in a more tender and flavorful final product.
  • Add sour milk to sauces and dressings for a creamy texture and subtle tangy flavor. It can also be used to make homemade cheese, like farmer's cheese or paneer.
  • Use in quick breads and cakes to create a moist and flavorful outcome. The acidity in sour milk reacts with baking soda, providing lift and a light texture to the baked goods.

Storage Tips

Sour milk is already in a state of spoilage; however, to slow further deterioration (if you intend to use it quickly for cooking), store it in a tightly sealed container in the refrigerator. Use within 2-3 days. Discard if it exhibits an off odor or visible mold.
