Baking great bread requires perfection, and perfectionism is baked into Hi-Rise Bread Company’s DNA: the bakery-cafe in Cambridge was opened in 1996 by a former food critic. Owner René Becker once wrote the dining column in Boston magazine. Today, Hi-Rise crafts more than a dozen varieties of bread every day, from baguettes to loaves of Nordic Rye. Each is good enough to be savored solo, but an extensive sandwich menu makes good use of the bakes in whimsically titled creations like Cash for your Hargo, a ciabatta roll stuffed with melt-in-your-mouth short rib and pickled onions.
