A few years ago, I walked into Eataly, the Italian food mega-emporium in Manhattan, for lunch and became so overcome by all the choices that I left without eating. Lame, I know, but I’m starting to feel like that at some cheese counters, especially when it comes to Swiss cheeses. I have way too many number-one favorites. And matters just got worse. Jumi, a respected Swiss producer, has recently targeted the U.S. market, and the cheeses are landing. You need to know them: all raw milk, all sublime. Steel yourself for some hard choices.
