My recipe needs cup of buttermilk → every ratio below adjusts

Milk + Lemon Juice

1 cup milk + 1 tbsp lemon juice

The acidity from the lemon juice helps cut through the fat of the Alfredo, though it must be added carefully to prevent the cheese from breaking.

1 cup kefir

As a direct 1:1 substitute, plain kefir adds a pleasant tang and creamy consistency that integrates well into the hot sauce.
