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?
