⭐ Soy Milk + Vinegar (Best Vegan Option)
1 cup soy milk + 1 tablespoon white vinegar (let sit 5 minutes)The acid in vinegar curdles the soy milk, creating a tangy, slightly thickened liquid that mimics buttermilk’s acidity and consistency. This acidity is crucial for breaking down meat proteins and tenderizing.
Allow the mixture to sit for 5 minutes to fully curdle before use. Use unsweetened soy milk to avoid unwanted sweetness.
While the flavor is not identical, it provides a comparable tenderizing effect and moisture level, making it suitable for vegan and dairy-free marinades.
