Book excerpt: The best in wurst from around the world, with enough sausage-themed stories and pictures stuffed between these two covers to turn anyone into a forcemeat aficionado. Lucky Peach presents a cookbook as a scrapbook, stuffed with curious local specialties, like cevapi, a caseless sausage that’s traveled all the way from the Balkans to underneath the M tracks in Ridgewood, Queens; a look into the great sausage trails of the world, from Bavaria to Texas Hill Country and beyond; and the ins and outs of making your own sausages, including fresh chorizo.
