yes, the main thing is to add sour cream, otherwise any cottage cheese doesn't taste very good

I have a separate issue with sour cream. I don't eat it in any form that preserves its "sour cream flavor." That is, pelmeni with sour cream – yuck. Cottage cheese with sour cream – yuck. Sour cream by the spoonful – yuck-yuck-yuck, what is that, why did you scoop that up, aaaah?!
However, sour cream is a good addition to dishes. Some bland vegetable soup is only conditionally edible on its own, but with sour cream, it gains fat and protein, and it becomes edible. Sour cream goes well in mushroom soup. Pelmeni – you can stew them in the oven with sour cream and cheese, it's a great thing. In short, sour cream is for me – purely a component of certain suitable dishes, in no case a "sauce."
