Thanks for the concern Tiarella! I've pierced it today, and I have survived to this point. It looks like a swiss, and tastes like one too. I'm thinking it picked up a wild PS somehow. After having a small nibble, I'm waiting to see if anything untoward occurs. Vanessa has ventured a taste as well and quite likes it, so I figure it is safe (she has a good "off taste" detection skill). Still, we'll wait it out before letting the kids try. It's quite tasty, though a slight bitterness on the finish. But not as much as I get on some other cheeses, so nothing surprising.
