Cultured Buttermilk: A Versatile Dairy Ingredient
Cultured buttermilk is a fermented dairy product that has been a staple ingredient in many cuisines for centuries. Originating from the leftover liquid after churning butter from cream, cultured buttermilk has a distinct tangy flavor and thick, creamy texture that lends itself well to a variety of culinary applications.
Fermented milk drinks resembling buttermilk have been part of dairying cultures since ancient times, though the specific term "buttermilk" describes a much later, Western European practice. In the American South, buttermilk has long been a beloved ingredient, often used in traditional recipes like biscuits, pancakes, and fried chicken.
Traditional buttermilk was the liquid left behind after churning cream into butter, but most cultured buttermilk sold today is made a different way: dairies add lactic-acid-producing bacteria directly to pasteurized low-fat or skim milk to recreate that same tang and thickness, largely independent of actual butter production.
In terms of its flavor profile, cultured buttermilk is characterized by a tangy, slightly sour taste, with a creamy, thick consistency. This distinctive flavor is a result of the fermentation process, during which lactic acid-producing bacteria, such as Lactobacillus and Streptococcus, convert the lactose in the milk into lactic acid.
Cultured buttermilk is a versatile ingredient that is commonly used in a wide range of culinary applications. In baking, it is a key ingredient in many recipes, including biscuits, pancakes, waffles, and quick breads, where it helps to create a tender, moist crumb. It is also used in marinades and dressings, where its tangy flavor can help to tenderize meats and balance the richness of other ingredients.
Beyond its use in baking and sauces, cultured buttermilk is also a popular ingredient in various cuisines around the world. In Indian cuisine, it is used to make popular dishes like raita, a cooling yogurt-based condiment, and lassi, a refreshing yogurt-based drink. In the Middle East, buttermilk is often used in savory dishes like fattoush, a salad made with toasted pita bread and vegetables.
When it comes to pairing cultured buttermilk with other ingredients, its tangy flavor pairs well with a variety of sweet and savory elements. In baking, it complements the richness of butter, eggs, and sugar, while in savory applications, it can balance the heat of spices or the creaminess of sauces. Some common complementary ingredients include fresh herbs, citrus, honey, and various types of fruit.
