Aida is a new small-batch snack operation, born out of a new New York incubator called Foodworks, that makes the best crackers we've ever eaten. At $9 for a 5.5-ounce box of Sourdough Crackers, they better be, but after tasting a couple of the wafer-thin crisps, I found myself scrutinizing the ingredient list, searching in vain for the parmesan that must be there to explain the cheesy, umami intensity of their flavor. There is none. But there is butter, and olive oil, and sea salt to amplify the twangy taste of the sourdough starter that goes into these crackers, which are shatter-crisp with a hint of layered flakiness, yet sturdy enough to withstand a schmear of chevre. Despite those fatty additions, the crackers don't film your fingers with grease the way, say, Ritz do, and for all their I need to eat another 20 of these right now deliciousness, they don't upstage the cheeses and nut butters we've paired them with. They are simply the perfect crackers.
