Gorgonzola is a type of blue cheese. Gorgonzola is known to be milder in taste with less of a funky taste and it is softer than some of the other blue cheese varieties. That let’s it soften up in this dish. A good Gorgonzola substitute would be Cambozola. This is a creamy, soft-ripened Camembert-type cheese with streaks of blue cheese. It melts really well and is even more mild than Gorgonzola. I’d recommend either of these if you are just being introduced to blue cheese.
