Mix all of the ingredients in a blender for a minute or two or until the consistency is smooth and creamy.
Alternatively, you can also whip your tofu sour cream by hand using a whisk - or use an immersion blender or food processor.
Taste and adjust the tart flavors by adding more lemon, vinegar, or both - and, as always, adjust the salt to preference.
Chill your homemade sour cream in a covered container until ready to serve.
