I love to bake but can't justify buying buttermilk for the odd time a recipe calls for it. Instead, I add vinegar to milk to replicate the buttermilk.(it works perfectly). At the same time, I LOVE to bake with coconut milk, substituting it for milk in the recipe. My question is, can I add vinegar to coconut milk and get the same results when substituting it for the buttermilk?

    Not directly answering that question: Curdling with acid works on soymilk too, less so on coconut milk. Jul 12, 2016 at 9:33

    You might look for buttermilk powder - it will keep longer, so it makes more sense for occasional uses.

No, you cannot. Cow milk has proteins, which curdle when exposed to acid, thickening the whole thing. Coconut milk is simply a suspension of fat in water, with very few carbohydrates and practically no proteins. You cannot curdle it with acid.


Yes,it can! Coconut buttermilk - made with full fat coconut milk and vinegar can be substituted in most recipes for baking. It's a wonderful alternative for those who are dairy intolerant or vegan. It works great in biscuits! Here's a recipe from the internet that I have used with success. https://cooknourishbliss.com/2012/08/08/cream-biscuits/
