Uses
Buttermilk adds a gentle tang and helps create light, tender textures in both sweet and savory recipes. Its natural acidity reacts with baking soda and baking powder for lift. This makes it a key ingredient in classic comfort bakes and creamy dishes. Here are some common uses of buttermilk:
Pancakes, waffles, and muffins: Give a fluffy, soft crumb, tender texture, and subtle tang to regular and gluten-free pancakes, grain-free scones, waffles and muffins.
Quick breads and biscuits: Buttermilk reacts with leavening agents for a higher rise and tender bite just like in this sweet potato cornbread.
Cakes and cupcakes: Adds moisture and balances sweetness in chocolate or spice cakes.
Fried chicken or tofu: The lactic acid in buttermilk tenderizes proteins and helps coatings cling for crisp, flavorful crusts.
Fish, fries, onion strings, or veggie fritters: It adds moisture while keeping batter light like in these gluten-free onion strings.
Salad dressings: Buttermilk provides tang without heaviness to creamy dressings just like in this dairy-free ranch dressing.
Dips and slaws: Its acidity brightens creamy bases.
Glazes: Mixed with powdered sugar for a light, tangy icing.
What is the best substitute for dairy-free buttermilk
If you are looking for a healthy alternative, these simple ingredients are the best options for replacing buttermilk in dairy-free or vegan baking and other recipes. Acidic ingredients like lemon juice or apple cider vinegar create a chemical reaction when mixed with a plant-based milk alternative that replicates the properties of regular buttermilk.
1. Plant Milk + Lemon Juice or Vinegar
Combine 1 cup unsweetened dairy-free milk (almond, oat, soy, coconut, or cashew milk) with 1 tablespoon lemon juice or apple cider vinegar or white vinegar. Stir and let sit for 5-10 minutes to curdle slightly. This option is great for pancakes, muffins, quick breads, and cakes. Apple cider vinegar will give the mixture a more tangy flavor than regular white vinegar.
