How to make sour cream chip dip
Use parmesan cheese.
Measure 16 ounces (454 g) of sour cream to a mixing bowl. Then add cup (50 g) of parmesan cheese and 1 tablespoon of dijon mustard.
Stir to combine and then add salt and pepper to taste. Add the salt a pinch at a time, though, since the parmesan is already pretty salty.
