Potage Madeleine

Potage Madeleine (Madeleine three-purée soup) teaches composition. Artichoke leads, haricot bean gives body, and Soubise brings the quiet sweetness of onion; measured correctly, they stop tasting like separate vegetables and become one rounded, savory whole. The one true thing to know before touching a pan is this: measure the finished purées, not the raw ingredients. Their proportion is the dish.

The source assumes a saucier with three finished purées and white consommé waiting on the stove. At home, one saucepan can cook the components in sequence, a blender replaces the pounding, and a fine-mesh sieve does the final work. A true white consommé is splendid, but pale unsalted chicken stock strained very fine is the honest home equivalent; once opaque purées enter the pot, consommé clarification is brigade scaffolding, while clean flavor and body still matter. The quantities here preserve the source proportions while making about two quarts for one cook, one stove, one evening.

Cooking the components separately, measuring them precisely, passing the combined soup, poaching the sago in stock, and whisking in real butter all stay. Those steps are the dish. Before you begin, set out a measuring jug: measuring the three finished purées is the step that decides Potage Madeleine.
