I have no use for sour cream as a condiment. I actively avoided it for years but of late I'll occasionally use it to make creamy salsa.
I make some surprisingly solid breaded chicken with sour cream.
Dip tenders in sour cream, then dip them again in crushed up Cheez-its and cayenne pepper. That is the only use I really have for it. Quick, easy snack to eat during sporting events.
If it comes on a Mexican dish, I just don't ask for no sour cream like I used to. It doesn't bother me anymore.
