Purée de Haricots Blancs, otherwise Soissonnaise

Purée de Haricots Blancs, otherwise Soissonnaise

Created by Chef Juliette

Based on No. 637, Purée de Haricots Blancs, otherwise Soissonnaise, from Le Guide Culinaire (1907) by Auguste Escoffier

Soissonnaise makes a silken soup from the plainest pantry: white beans cooked with carrot, bouquet garni, and clove-stuck onion, passed fine, loosened with white stock and milk, then glossed with butter.

Purée de Haricots Blancs, dite Soissonnaise (silken white bean soup), teaches the first law of every legume purée: smooth is not the same as refined. A machine can break a bean down, but a tamis, a fine sieve, removes its skins, leaving an ivory soup with body and no mealiness. The sieve is the dish; everything around it is support.

The source entry assumed a stock never off the fire, a saucier free to skim the pot through service, and a tammy wide enough for brigade work. Your honest equivalents are pale unsalted chicken stock, one heavy pot, a food mill, and a fine-mesh tamis. Its good half-pint of dried beans is already nearly right for a home pot, so I preserve it as 1¼ cups, about 250 grams, and finish at roughly two quarts. Repeated holding was service scaffolding and can go, while the slow cooking and final sieve stay. One cook, one stove, one evening.

The finished Soissonnaise should pour in a broad ivory ribbon, rich with bean but never stodgy, with milk softening the edges and butter giving the surface its quiet gleam. Cook the beans until they collapse between two fingers before you reach for the tamis. That tenderness is the one step that decides everything.

Soissonnaise belongs to Soissons and the Aisne valley in northern France, where the large white haricot became an emblem of the city and gave its name to preparations built on white beans. From household pots the purée entered the classical repertoire, where cooks refined it through a tamis, diluted it with white consommé and milk, and finished it with butter. Despite its place among cream soups, this version is thickened by the bean itself; velouté and cream are separate treatments the source names as alternatives, not ingredients quietly folded into the purée.

The technique, the tradition, and the story behind every dish.

Equipment Needed

  • Food mill fitted with a fine disc
  • Fine-mesh metal tamis or sturdy sieve
  • Flexible bowl scraper
  • Wide skillet for the bread dice

Instructions

  1. 1

    Quick-soak the beans

    Put the rinsed beans and cold water in a heavy 5 to 6-quart pot. Bring to a full boil for 2 minutes, cover, remove from the heat, and leave undisturbed for 1 hour. This quick soak is the honest one-evening equivalent of an overnight soak; it shortens the waiting without replacing the slow cooking that gives the purée its body.

  2. 2

    Cook with aromatics

    Add the carrot, clove-stuck onion, and bouquet garni to the soaking pot. Bring the water back slowly, skim away the first grey foam, then hold the beans at a gentle simmer with the lid slightly ajar for 75 to 105 minutes. Add hot water whenever the beans threaten to rise above the liquid. When they are nearly tender, stir in 1 teaspoon of the salt. The beans are ready only when one collapses into a smooth paste between two fingers; if they remain chalky after the expected time, give them more hot water and patience. Older beans simply take longer.

  3. 3

    Pass through the tamis

    Set a colander over a bowl and drain the beans, reserving all their cooking liquor. Remove the bouquet garni and the whole clove, but keep the cooked onion and carrot with the beans. Work the beans and vegetables through a food mill, moistening them with 3 to 4 tablespoons of cooking liquor, then rub that purée through a fine-mesh tamis with a flexible scraper. If the purée clogs the mesh, loosen it one tablespoon at a time with more liquor; forcing a dry mass through only pushes skins into the soup. A blender alone is brigade scaffolding in reverse, quick but less refined. The final sieve must stay.

  4. 4

    Set the consistency

    Return the sieved purée to the cleaned pot. Whisk in 2½ cups of the white consommé or pale chicken stock a little at a time, followed by all but 2 tablespoons of the milk. Bring it up slowly over medium-low heat, stirring across the bottom so the bean starch cannot catch. Add enough of the remaining stock or reserved cooking liquor to make about 2 quarts. The soup should coat a spoon lightly and pour from it, never sit in a mound.

  5. 5

    Dépouiller the soup

    Dépouiller, skim the surface, while the soup trembles at the gentlest simmer for 10 to 15 minutes. Remove every patch of pale foam as it gathers, then stir along the pot floor before it can scorch. If the soup is too thick, whisk in more stock or cooking liquor; if it is too loose, simmer it uncovered until the spoon carries a light veil. Ça se rattrape. Do not reach for flour, because the bean supplies the proper body.

  6. 6

    Brown the bread dice

    While the soup settles, melt 2 tablespoons of the butter in a wide skillet over medium heat. Add the bread dice and toss them patiently until every side is crisp and butter-gold, with darker brown corners here and there. Transfer them to a plate at once. Leave them in the hot pan and they continue browning past the point of pleasure.

  7. 7

    Monter au beurre

    Remove the soup from the heat. Monter au beurre, finish with butter, by whisking in the remaining 4 tablespoons a piece at a time until the surface gleams and no oily beads remain. Season with the white pepper and remaining salt as needed. Do not boil it again. If the butter separates on the surface, whisk in the reserved 2 tablespoons of cold milk off the heat until the emulsion returns. Ladle into warm bowls and add the bread dice at the last moment so they stay crisp. À table!

Chef Tips

  • True haricots de Soissons are exceptionally large and creamy when you can find them. Great Northern beans are the most practical substitute; choose a recent bag from a shop with good turnover, because elderly beans can simmer for hours and remain stubborn.
  • Keep the stock pale. A roasted brown stock muddies both the colour and the delicate taste of the beans; homemade white consommé is splendid, but a good unsalted chicken stock is the honest home equivalent.
  • The tamis is not ceremony. It removes the skins that make a blended bean soup taste faintly sandy. A sturdy fine-mesh metal sieve and a flexible bowl scraper do the work perfectly well.
  • The source also permits velouté and cream versions, but they are different branches of the same family. This purée needs neither roux nor cream; its structure comes from the sieved beans, milk, and final butter emulsion.
  • Serve the Soissonnaise with roast poultry, baked ham, or simply a green salad and more bread. A dry Chenin Blanc has enough freshness for the milk and butter without bullying the beans.

Advance Preparation

  • For a shorter cooking day, soak the beans overnight in plenty of cold water. Drain them, begin Step 2 with the listed 10 cups of fresh water, and expect the simmer to take about 60 to 90 minutes.
  • The soup can be prepared through the dépouiller step up to 2 days ahead. Cool it promptly, cover, and refrigerate; reheat it gently with a little stock or milk, then add the finishing butter only when you are ready to serve.
  • For longer storage, freeze the sieved bean base with its stock but without the milk or finishing butter for up to 2 months. Thaw it in the refrigerator, warm gently, and complete the recipe with the milk and butter.
  • The bread dice may be browned a day ahead and kept airtight at room temperature. Add them only at the table.
