Milk and lemon juice
There are other uses for lemons than only as a health supplement and beauty aid. You may make buttermilk using lemon juice since it has acid. To replace buttermilk in baking recipes, all you need is milk and lemon juice.
Add 1 tablespoon (15 mL) of lemon juice to a liquid measuring cup to get 1 cup (240 mL) of the buttermilk substitute. Once the milk has been added to the 1-cup line (240 mL). Stir to combine, and let the mixture rest for at least 5 to 10 minutes before using. Lemon juice is available in both bottled and freshly squeezed varieties. Preservatives like sodium benzoate and sodium sulfite are commonly found in bottled varieties. But you should keep in mind that some people's symptoms of asthma may be worse by sulfites.
