Sour cream is not a substitute for cheese, it is not "cheese part 2" just add more cheese ffs.*** If you want that texture just use queso it is 10,000 times better than just adding sour cream. Having both is insane.
The last thing I want inside my giant warm baked potato, or giant warm burrito, is a huge glob of ice-cooled fucking sour cream. I don't care if it's Americanized tacos I don't care if it's Mexican tacos sour cream has no place inside that s*** it, has no place on my nachos, it has no place anywhere near my hot food.
Any queso which is made with cream frieche or sour cream as a base is also heresy. Make a roux like an adult, and melt the cheese into it also like an adult. This is why Chipotle's queso tastes like thigh sweat after walking around Disney World for 7 hours, cuz they use sour cream as a base.
**title says most things. There are some chip dips I'm fine with it as a base, I dont think it "tastes bad" in everything flat out. Mostly dislike it in hot foods placed as a condiment, or as a base for queso.
*** so to clarify, ya a few friends of mine have told me things like "it's like putting another kind of cheese on it for me". This may be a unique thing to these couple people but hey I heard this more than once from friends who eat sour cream on stuff.
