Ingredients for Buttermilk Substitute

- 1 scant cup* milk (use any type of milk you have on hand)
Step-by-Step Instructions
- Pour 1 Tablespoon of lemon juice (or white distilled vinegar) into a liquid measuring cup.
- Add milk to the measuring cup until the liquid reaches the 1-cup line (check at eye level for accuracy).

Why This Buttermilk Substitute Works
This simple swap uses lemon juice or vinegar to acidify the milk, mimicking the tangy flavor and slight thickness of real buttermilk. It’s perfect for baking recipes like pancakes, muffins, or cakes where buttermilk is called for. The slight curdling is normal and ensures the right texture for your dish!
Recipe Variations to Try
If you’re out of lemon juice or vinegar, try using cream of tartar (1 ¾ teaspoons per cup of milk) for a similar effect. For a dairy-free option, use plant-based milk like almond or soy, though the texture may vary slightly. Experiment to find your favorite!
Time-Saving Tips for Busy Cooks
Pre-measure your lemon juice or vinegar and keep it handy in a small container. This way, you can quickly mix up your buttermilk substitute whenever a recipe calls for it. No need to run to the store—this hack takes just 5 minutes!
Common Questions Answered
Wondering if this substitute works for all recipes?
It’s best for baking rather than drinking or making dressings. Also, if your recipe calls for more than 1 cup of buttermilk, simply scale up the ingredients proportionally. Easy as pie!
Special Notes for Perfect Results
Use whole milk for the best texture, but 2% or skim milk will work in a pinch. Let the mixture sit for 5-10 minutes before using to allow the milk to thicken slightly. This ensures your baked goods turn out light and fluffy every time!
