My recipe needs cup of buttermilk → every ratio below adjusts

Milk + Lemon Juice

1 cup milk + 1 tbsp lemon juice

The acid in lemon juice reacts with baking soda to create the lift needed for fluffy cakes and biscuits.

1 cup kefir

As a fermented dairy product, kefir mimics buttermilk's tang and thickness while ensuring a tender crumb.

1 cup soy milk + 1 tbsp lemon juice

Unsweetened soy milk curdled with acid works as a viable vegan alternative that provides necessary acidity for leavening.
