USA seems to have a lot of cheese that I have never heard of. SO what does a fontina look/taste like.
Well it's an Italian cheese actually, it's just being sold here. It's a creamy, not very sharp, but flavorful meltable cheese.
From
Wikipedia:
Fontina has a mild, somewhat nutty flavor, while rich, herbaceous and fruity. It melts well.
I really like it in omelettes.
