So it turns out I'm now allergic to blue cheese. I bought a beautiful wedge of Roth Käse Buttermilk Blue, and had a bit on a cracker.
Instant itchiness all over my mouth. And, get this, I'm not allergic to penicillin.
But, like with avocado, I'm still going to eat blue cheese, in moderation. Especially this Roth Käse, because it's tangy, creamy, and utterly delicious - and only $11/lb at my local grocery store. (You can buy a whole 6lb wheel direct from the manufacturer for $7.43/lb. A 50% markup for a small cut isn't bad!)
