Some people like as much fat as possible on their bacon, but if you're like me, an equal amount of meat and fat is best. If you want to check the meat-to-fat ratio, flip that package around.
No, I'm not talking about the nutrition facts (looking at those might ruin bacon for you). I'm referring to the "fat window" that's usually visible on the packaging. As Paul Lukas at Bloomberg explains, standard packages of bacon come in "shingle packs," where the slices are fanned out. This often gives the illusion that a package of bacon is much leaner than it really is. The fat window on the back of the package, however, gives you a clear view of what those slices really look like.
Now if you find a package that looks like it's all fat, you can make a more informed choice depending on what you prefer. This might seem obvious or frivolous to some of you, but it's definitely going to change the way I shop for bacon.
