Another Alton Brown masterpiece from the American Classic I Good Eats episode, 2007. I list the original full measurements that he gave below. However, I'm not a big raw onion person, so used only half a sliced onion, and, for health reasons, cut the amount of bacon in half, which didn't diminish the flavor of the recipe in the least. I could happily gorge on spinach salad all day! **Alton recommends loose leaf Savoy or semi-Savoy spinach, if available, eschewing the bagged varieties for freshness reasons. Since I couldn't find any loose leaf, however, I just carefully checked the bagged kind for any brown or slimy areas, and went organic for an extra health kick. **Alton has his own method of hard-boiling eggs. I simply put them in hot water with an "Eggsact Eggtimer" and simmer them until the device reads Hard! Have never had a problem with grey yolks, etc. **If you're lucky enough to find slab (unsliced) bacon, it's easiest to wrap it in parchment paper and slice it yourself to a generous 1/4" thick, discarding the paper ribbon when done. **Finally, if you don't have red wine vinegar on hand, I got away with 2 T balsamic vinegar plus 1 T apple cider vinegar.
