"The most crucial component of any sandwich is balance: of flavors, of textures, of bread to filling," Rob Patronite and Robin Raisfeld write as a preface to their list of New York's 101 best sandwiches. Not to be outdone, Grub Street compiled a list of Boston's own noteworthy sammies. A few are so good that you can only get them at certain times, like the Cutty's porchetta (Saturdays) or the limited-to-lunchtime crab melt panini at Barlow's.
