@ajstar I like your article, thanks for sharing. Have you tried them yourself? They used to sell such burgers in the supermarket next to my house. I tried them and thought they were pretty nice. For me they had a nutty taste. Quite similar to the nutty flavour profile found in certain cheeses.
For anyone feeling a bit freaked out by such burgers, you could ease into it by sampling some fine cheese. Cheeses like Stilton, Mimolette and Comte have tasty mites on them.
