Condés au Fromage

Condés au fromage (cheese-topped puff-paste fingers) teach one exact lesson: Béchamel, a milk sauce thickened with a white roux, must be completely cold before the Gruyère and Parmesan dice go in. Warm sauce rounds their corners into itself; cold sauce holds them as small, distinct pockets until the oven takes over. That chilling is the dish, not a courtesy.

The original kitchen assumed puff-paste trimmings waiting at the pastry bench, a saucier reducing Béchamel, and enough hands to make one tray while another service continued. Here, one chilled ribbon prepared through Allumettes (No. 2299), a one-quart saucepan, parchment, and a measured home oven do the same work. Separate stations and brigade quantities are scaffolding and can go; the reduction, full chilling, cayenne, and tiny cheese dice stay. The quantities below make one generous dinner-party tray. One cook, one stove, one evening.

Expect butter-gold edges, a crisp laminated base, and an ivory cheese layer freckled bronze across the top. Reduce the Béchamel until it mounds, then cool it all the way through before folding in the cheese. If the dice begin to smear, stop and chill the mixture again. Ça se rattrape.
