Traditional buttermilk is the thin, mildly tangy liquid left behind after churning heavy cream into butter. This simple, old-fashioned buttermilk is perfect for baking, cooking, and adding moisture to recipes like pancakes, biscuits, and cornbread.
2 cups heavy whipping cream
Pour the heavy whipping cream into a mixer or food processor.
Mix until the cream separates into solid butter and liquid buttermilk.
Strain the liquid into a clean container and reserve for use.
Store the buttermilk in the refrigerator until ready to use.
This is traditional buttermilk, not cultured store-bought buttermilk.
Texture will be thinner and flavor milder than store-bought.
For extra tang, add 1–2 teaspoons lemon juice or vinegar per cup if needed.
