Coconut milk with apple cider vinegar is a unique combination of ingredients that has many uses in cooking - and when coconut texture matters, see shredded coconut substitute ideas for texture.

The flavor and texture are slightly sweet from the coconut milk and tart from the apple cider vinegar, creating an enjoyable cooking experience.

You can use this combination as a non-dairy substitute for traditional buttermilk in any recipe--just combine one cup of coconut milk with two tablespoons of apple cider vinegar and allow it to sit for about 10 minutes.

Coconut milk with apple cider vinegar is a delicious dairy-free alternative that makes baking more flavorful and accessible.

The combination creates a flavorful beverage that can also be used as a dairy-free substitute for buttermilk in baking, marinades, dressings, and other recipes.

To use as a substitution for buttermilk in your recipe, simply mix equal parts almond milk and fresh-squeezed lemon juice and let it sit until it thickens slightly.

With its tasty flavor, creamy texture, and easy preparation, almond milk with lemon juice is the perfect ingredient to improve your favorite dishes.

4 - Rice Milk with White Vinegar

Rice milk with white vinegar is a surprisingly delicious combination - and when sticky rice is needed, check glutinous rice substitute suggestions for stickiness.

The ingredients are simple and straightforward: just rice, water, and a small amount of white vinegar.

Mixing the two together creates a creamy texture that mimics that of real buttermilk.

The taste of the rice milk itself is mellow, almost sweet, and the acidity from the white vinegar balances it perfectly.

It can be used as a non-dairy substitute for buttermilk in any recipe that calls for it; all you need to do is add some extra water to compensate for the amount of liquid lost due to the addition of the vinegar.

So if you are looking for an easy and delicious vegan alternative to regular buttermilk, then rice milk with white vinegar might just be your answer.
