If the recipe calls for milk and you have sour how do alter baking powder soda?

Here's a simple rule of thumb: for every 1 cup of sour milk, you'll need to add an additional 1/4 teaspoon of baking soda. So, if a recipe calls for 1 cup of milk, you would add 1/4 teaspoon of baking soda. If it calls for 2 cups of milk, you would add 1/2 teaspoon of baking soda, and so on.

When adding baking soda to sour milk, be sure to stir it in gently until it is fully dissolved. This will help to ensure that the baking soda is evenly distributed throughout the mixture and that the final product has a consistent texture.

Also, please remember to reduce the baking powder in the recipe by half because the baking soda will act as a leavening agent.

For example, if the original recipe calls for 1 teaspoon of baking powder, you would only use 1/2 teaspoon of baking powder.
