Purée de Lentilles, otherwise Conti

Purée de Lentilles, dite Conti (silken lentil soup), teaches the discipline of refinement. Flavour is built with the whole aromatic garnish in the pot, but texture depends on removing every piece before the lentils are worked. Carrot, onion, and bouquet garni have already given what they owe; blend them into the soup and their fibres coarsen what should pass over the tongue like velvet.

The original kitchen assumed a saucier on staff, white consommé never off the fire, a mortar for pounding, and a tammy for sieving. This quantity is already sensible for a home pot, about two quarts, so I have converted its measures without disturbing the ratio. A prepared consommé replaces the perpetual stockpot, a blender replaces the mortar, and a sturdy fine-mesh sieve does the tammy's work. Hand-pounding was brigade scaffolding and can go. Sieving is the dish and must stay. One cook, one stove, one evening.

Conti should be savoury and satin-smooth, with lean bacon giving depth rather than smoke, butter supplying the final gloss, and little croûtons cracking under the spoon. If the purée tightens or stays coarse, ça se rattrape, and the method shows you where. Before you touch the pan, remember the step that matters most: the cooking garnish comes out before the lentils meet the blender.
