Bouillabaisse à la Marseillaise
Marseille's great fish stew, saffron-gold and garlic-scented, proves that a hard boil can be the careful choice: it binds olive oil into broth before the whole pot meets bread.

Potage Germiny
Created by Chef Juliette
Based on No. 724, Potage Germiny, from Le Guide Culinaire (1907) by Auguste Escoffier
Sorrel melted in butter, clear consommé, and a liaison of yolks and cream: Potage Germiny teaches the gentle heat that turns simple broth silken without letting the custard curdle.

Potage Germiny (sorrel soup bound with egg yolks and cream) teaches the most delicate liaison, the binding of hot liquid with yolks. One true thing decides it: once the liaison enters the saucepan, the soup may approach the simmer, but it must never boil. The yolks should thicken like crème anglaise, giving body without announcing themselves as egg.
The original method assumed a saucier watching the pan, white consommé waiting beside a stockpot that never went cold, and service timed to the minute. At home, one heavy saucepan, a wooden spoon, and an instant-read thermometer do the same work. The separate hands and holding pans were brigade scaffolding and can go; the finished consommé, butter-melted sorrel, last-minute liaison, and cold-butter finish are the dish and must stay. The source proportions are retained in a home batch of about two quarts. One cook, one stove, one evening.
When it lands correctly, the soup is pale green and glossy, sharpened by sorrel but rounded by cream and butter, with fine chervil pluches floating at the surface. Stir continuously through the final thickening and pull the pan at the first tremor around its edge. Those few minutes decide everything.
Potage Germiny belongs to the Parisian grand-kitchen table, where it took the name of the Comte de Germiny and turned the familiar French pairing of sorrel and eggs into a formal first course. It passed through the classical canon as a model for a whole family of delicate vegetable soups. Its structural surprise is that neither roux nor purée supplies the body; the liaison alone thickens it, a method classical cooks also applied to carrot, pea, and asparagus creams.
The technique, the tradition, and the story behind every dish.

- •Wooden spoon or heatproof spatula
- •Balloon whisk
- •Instant-read thermometer
- •Fine-mesh sieve for an emergency rescue
Instructions
- 1
Prepare the sorrel
Wash the sorrel in cold water, dry it thoroughly, and remove any tough stems. Stack several leaves at a time, roll them loosely, and cisel them, cutting crosswise into fine, even shreds. Wet leaves spit in butter and dilute the first stage, so take the drying seriously. Keep the cold finishing butter refrigerated until the final moment.
Sorrel bruises and darkens quickly once cut. Cisel it shortly before cooking, and use a sharp knife so the leaves are sliced rather than crushed. - 2
Melt the sorrel
Melt the 2 tablespoons of butter in a heavy 3-quart saucepan over medium-low heat. Add the sorrel and turn it through the butter for 3 to 5 minutes, until every shred has collapsed into a soft olive-green tangle without browning. This is a fonte, a gentle melting rather than a sauté. If the sorrel begins to catch at the edges, lower the heat and loosen it immediately with a spoonful of the measured consommé.

Add the consommé
Pour in the finished white consommé and stir well, lifting any sorrel from the floor of the saucepan. Bring the soup only to a bare simmer and cook for 4 to 5 minutes so the sorrel and consommé become one preparation. Avoid a hard reduction; the consommé is already finished and concentrated, and boiling it down would make the final soup too salty and coarse.

Make the liaison
Reserve 2 tablespoons of the cold cream for the possible rescue, then whisk the remaining cream with the egg yolks until perfectly smooth. Take the saucepan off the heat. Stir the soup continuously while pouring in the liaison in a thin, steady stream, then return the pan to the lowest heat you own. Stir in a patient figure eight, scraping the floor and corners, until the soup lightly naps the back of the spoon and reaches 170 to 175°F (77 to 79°C), about 5 to 8 minutes. You may see a faint tremor at the rim, but no bubble should break the surface. If a few tiny grains appear, remove the pan immediately and whisk in the reserved cold cream until smooth. Ça se rattrape. A hard boil produces firm curds that no honest finish can disguise, so stay beside the pan.
Without a thermometer, draw a finger through the soup coating the back of the spoon. The line should remain clean for a moment instead of flooding closed. - 5
Finish with butter
Keep the saucepan completely off the heat. If the reserved cream was not needed for rescue, stir it in now. Monter au beurre, finish by stirring in the cold butter a few cubes at a time, allowing each addition to disappear before adding the next. Do not return the soup to the burner; the butter should emulsify into a quiet gloss, not melt into an oily slick. Fold in the chervil pluches, ladle immediately into warmed soup plates, and serve. À table!
Chef Tips
- •Fresh sorrel is the dish, not a decorative herb. Its clean acidity cuts through twelve yolks, cream, and a heroic quantity of butter. Spinach with lemon makes a pleasant soup, but it does not make Potage Germiny.
- •Use a pale, well-seasoned white consommé with real body. A dark roasted stock muddies the colour and overwhelms the sorrel, while thin broth leaves the liaison carrying more weight than it should.
- •Keep the finishing butter cold. The temperature difference helps it disperse into the soup as a smooth emulsion; soft butter melts too quickly and can leave fat floating at the rim. We don't apologize for butter, but we do make it behave.
- •Serve Potage Germiny as a small first course rather than a large bowl. A dry Loire Sauvignon Blanc has enough acidity for the sorrel and enough restraint for the liaison.
- •Leftovers can be chilled promptly and kept for one day. Reheat over very low heat while stirring, stopping below 175°F (79°C). If the soup boils during reheating, the yolks can curdle.
Advance Preparation
- •Prepare the finished white consommé up to 3 days ahead and keep it chilled, or freeze it well in advance. Bring it only to a gentle simmer before adding it to the melted sorrel.
- •Wash and dry the sorrel up to 4 hours ahead, then wrap it loosely in a clean towel and refrigerate it. Wait to cisel the leaves until shortly before cooking so they retain their colour.
- •Separate the eggs and measure the cream several hours ahead, keeping both covered and cold. Whisk the liaison only when the consommé is nearly ready.
- •Do not complete the liaison and hold the soup for a dinner party. Prepare through the brief consommé simmer, lower the heat, and bind it just before serving; this final step is the dish, not service scaffolding.
