by

Have you ever been ready to bake your favorite recipe only to realize you’re out of buttermilk? Don’t let that stop you! Making buttermilk from milk and lemon juice is a simple kitchen hack that will save you a trip to the store. With just two ingredients and a few minutes, you can create a tangy substitute perfect for pancakes, cakes, biscuits, and more. This guide will show you everything you need to know to make buttermilk from scratch with milk and lemon juice, ensuring your baked goods turn out delicious every time.

Why Make Buttermilk at Home?

Buttermilk is a fantastic ingredient for adding moisture and a subtle tang to baked goods. It tenderizes gluten, which results in a softer and more delicate texture. It also activates baking soda, providing a better rise. Making your own buttermilk substitute with milk and lemon juice is convenient, cost-effective, and ensures you always have a buttermilk alternative on hand.

The Science Behind the Magic

When lemon juice is mixed with milk, the citric acid in the lemon juice causes the milk to slightly curdle. This imitates traditional buttermilk, which is made by culturing milk. The resulting mixture has a similar acidity and consistency, making it an ideal substitute in most recipes.

Simple Ingredients, Big Flavor

To make buttermilk from milk and lemon juice, you only need two readily available ingredients:

  • 1 tablespoon of lemon juice (fresh or bottled)
  • 1 cup of milk (any kind, including dairy and non-dairy options like almond, soy, or coconut milk)

Step-by-Step Guide to Homemade Buttermilk

Here’s how to make buttermilk with lemon juice in just a few easy steps:

  1. Measure Lemon Juice: Pour 1 tablespoon of lemon juice into a liquid measuring cup.
  2. Add Milk: Add milk to the measuring cup until it reaches the 1-cup line. You’ll use a little less than a full cup of milk to compensate for the lemon juice.
  3. Stir Gently: Use a spoon or fork to gently stir the lemon juice and milk together.
  4. Let It Sit: Allow the mixture to sit at room temperature for 5-10 minutes. You’ll notice the milk start to curdle slightly. Don’t worry if it doesn’t curdle much; it will still work as a substitute.
  5. Use in Your Recipe: Your homemade buttermilk is now ready to use in your recipe!

Pro Tips for the Best Results

  • Room Temperature Milk: Using milk at room temperature helps the curdling process.
  • Fresh Lemon Juice: Freshly squeezed lemon juice provides the best flavor, but bottled lemon juice works too.
  • Avoid Over-Mixing: Stir gently to combine, but avoid excessive stirring.
  • Use Immediately: This buttermilk substitute is best when used right after preparation.
  • Milk Options: Feel free to use any milk you have on hand. Whole milk and 2% milk will create a richer substitute, but skim milk and non-dairy alternatives work well too.

Scaling the Recipe for Different Needs

If your recipe calls for more or less than 1 cup of buttermilk, here’s how to adjust the recipe:

  • 1/4 cup buttermilk: ¾ teaspoon lemon juice + milk to fill to ¼ cup line
  • 1/3 cup buttermilk: 1 teaspoon lemon juice + milk to fill to ⅓ cup line
  • 1/2 cup buttermilk: 1 ½ teaspoons lemon juice + milk to fill to ½ cup line
  • 2/3 cup buttermilk: 2 teaspoons lemon juice + milk to fill to ⅔ cup line
  • 3/4 cup buttermilk: scant 2 ½ teaspoons lemon juice + milk to fill to ¾ cup line

Alternative to Lemon Juice: Vinegar

If you don’t have lemon juice, white vinegar or apple cider vinegar can be used as a substitute. Use the same method: combine 1 tablespoon of vinegar with enough milk to reach the 1-cup line.
