We're crazy about the House Fries from Michael and Christina Corvino’s eponymous restaurant in Kansas City, Missouri—scoop-shaped, well-seasoned morsels that marry the airy puff of pommes soufflées to the meaty crunch of a good french fry. Their secret? An eight-step method (below) that entails rinsing the spuds of excess starch, simmering them in salty vinegar water to season each fry perfectly, then air-drying and frying them twice, with a stint in the freezer in between. Serve the finished fries with XO sauce and aioli as they do at Corvino, or dunk them in spicy mayo.
