⭐ Coconut Milk + Lemon Juice (Best Vegan Option)
1 cup coconut milk + 1 tablespoon lemon juice (let sit 5 minutes)Coconut milk provides fat and moisture, while lemon juice adds acidity to mimic buttermilk’s properties. The acid helps tenderize meat proteins and retain moisture.
Let the mixture sit for 5 minutes to curdle slightly. Use full-fat coconut milk for best texture. Be aware the coconut flavor can subtly influence the burger’s taste, which may or may not be desirable.
This substitute is suitable for dairy-free diets but results in a different flavor profile and slightly different texture compared to traditional buttermilk.
