I love feta cheese, and I can't get enough of it, just like my family. But unlike them, I only eat it raw. I can't stand the grilled feta sandwiches my mother eats every morning for breakfast, and the reason is that, when the feta is grilled, it turns terribly salty and sharp.
The reason can't be just melting, because I enjoy lots of dishes which are baked with feta in the filling, as long as it doesn't get any direct heat.
What is the reason for this taste change? Can it be prevented?
