⭐ Coconut Milk + Lemon Juice (Best Dairy-Free Option)
1 cup full-fat coconut milk + 1 tablespoon lemon juice (let sit 5 minutes)The acidity from lemon juice curdles the coconut milk, creating a tangy, dairy-free alternative to buttermilk. The acid helps tenderize the beef and provides a similar flavor balance.
Use full-fat coconut milk for richness and allow the mixture to sit for 5 minutes before adding. Be aware the coconut flavor can subtly alter the stew’s traditional taste.
This substitute works well for dairy-free diets but may result in a slightly sweeter and tropical flavor profile compared to classic buttermilk.
