⭐ Silken tofu blended with lemon juice (Best Dairy-Free Option)
3/4 cup blended silken tofu + 1 teaspoon lemon juice per 1 cup sour cream Quick tip: Dairy-free and vegan option; may slightly alter texture and flavor.
Silken tofu provides a smooth, creamy base that can mimic the texture of sour cream when blended with lemon juice to add acidity. This combination works chemically to approximate the fat and tang balance needed in the custard.
Blend silken tofu until completely smooth, then mix in lemon juice. Use 75% of the sour cream volume to avoid excess moisture. Because tofu lacks dairy fat, the custard may be less rich.
The resulting custard will be less creamy and slightly more neutral in flavor, with a subtle bean-like undertone. It is a suitable vegan alternative but may deviate from the classic mouthfeel and taste.
