⭐ Coconut Milk with Lemon Juice (Best Vegan Option)

1 cup full-fat coconut milk + 1 tablespoon lemon juice, let sit 5 minutes

Quick tip: Dairy-free alternative that adds acidity and fat, but imparts a mild coconut flavor.

Full-fat coconut milk provides the necessary fat content similar to buttermilk, and the addition of lemon juice introduces acidity to mimic buttermilk’s tang. This combination helps maintain the custard’s creamy texture and balance of flavors.

Let the mixture sit for 5 minutes to allow slight curdling before use. Be aware that coconut milk’s natural flavor will subtly influence the final taste.

The resulting Crème Brûlée will be dairy-free with a slight coconut undertone, which may be desirable or not depending on preference, but the texture remains smooth and rich.

Soy Milk with Apple Cider Vinegar

1 cup soy milk + 1 tablespoon apple cider vinegar, let sit 5 minutes

Quick tip: Plant-based substitute with acidity, but lower fat content may yield a lighter custard.

Soy milk acidified with apple cider vinegar provides the necessary acidity to mimic buttermilk’s effect on egg proteins, though its fat content is lower than dairy buttermilk. This can result in a lighter custard texture.

Allow the mixture to rest for 5 minutes before use to ensure proper curdling. Use full-fat soy milk to maximize richness.

The final custard will be less rich and slightly lighter in texture, with a mild bean-like flavor that may subtly alter traditional Crème Brûlée notes.
