Well, I recently went to Whole Foods and purchased the Kerrygold Cashel blue for a burger I was making, and I was absolutely floored by the funkiness of the cheese. It was so strong and so amazing on the burger. It melted into an almost oily state and flavored the entire burger from inside to outside.
I was hoping to get some other brands that work well on a good burger, cooked medium rare of course. I like strong blue cheeses and also slightly creamy. Crumbly dry variations really aren't my thing. I tried the Rogue Smokey Blue on a burger and it never really softened and really wasn't very flavorful or strong enough for my palette.
P.S. - My favorite cheese in the world is Le Petite brie. So damn strong and ammoniated. Good baguette + preserves + Le Petite = Amazing.
