Purées

Purées de légumes (vegetable purée soups) teach one true thing before you touch the pan: know where the body will come from. Lentils, dried beans, and floury potatoes bring their own starch. Carrots, pumpkin, turnips, celery, and tender herbs do not, so they need rice, potato, or butter-fried bread crumb to cohere. This carrot purée uses rice at the classical proportion, enough to bind the soup without announcing itself in the bowl.

The original formula assumed a saucier beside the pot, ordinary white consommé never far from the fire, brigade quantities, and a tamis (drum sieve) broad enough to process them. Your honest equivalents are a light chicken stock, an immersion blender, and a fine-mesh sieve. This batch begins with one pound of carrots and keeps the book's exact proportion of three ounces of rice; only the volume and the number of hands have changed. One cook, one stove, one evening.

The enormous pot and its attendant cook were scaffolding. The quiet simmer, careful skimming, butter added away from the heat, and second passage through the sieve are the dish, so those remain. The step that matters most is the finish: take the pan completely off the fire before the butter enters, then strain once more for the texture a proper purée promises.
