Ensure that the coconut cream is well chilled. You can refrigerate it for a few hours or overnight to separate the cream from the liquid.
Scoop out the thickened coconut cream (leaving any watery residue behind) into a mixing bowl.
Add 1 tablespoon of lemon juice to start. Mix well until smooth and incorporated. Taste and adjust the tartness by adding more lemon juice if needed.
Optionally, add a pinch of salt to enhance the flavor, but this step is entirely optional.
Notes
This substitute provides a creamy, tangy flavor similar to sour cream and is an excellent alternative for those looking for a dairy-free or vegan option. Adjust the lemon juice to your taste preferences for the desired level of tanginess.
