It doesn't taste like cheese or sour cream.

Do you know what Ricotta is? It tastes like that. In fact, it's made the same way.

Oh, or the "Paneer" in for example, Sag Paneer?

Tastes like that.

When they say sour cream I think they mean as opposed to like, Cheddar or Gouda, but it's SO NOT "sour" like sour cream is. It doesn't have that "zing."

I hope that helps!
