Potage Marigny

Ingredients

Equipment Needed

• •3- to 4-quart heavy saucepan
• •Small saucepan for blanching
• •Fine-mesh skimmer
• •Sharp chef's knife
• •Whisk
• •Fine-mesh sieve or immersion blender for rescue

Instructions

1. 1

   Ready the Fontange

   Prepare the Potage Fontange fully according to its own entry, then measure about 8 cups (1.9 L / 1.9 kg). Treat it as a finished component, exactly as the source directs. Taste it cold enough to judge the seasoning clearly, cover it, and set it aside while you prepare the garnish.

2. 2

   Cut the lozenges

   Slice the trimmed green beans on a long diagonal into neat ¼-inch (6 mm) lozenges, small diamond shapes that will sit comfortably on a soup spoon. Measure one level tablespoon after cutting, then measure one level tablespoon of peas separately. The quantities are deliberately modest: the garnish should interrupt the smooth soup, not crowd it.

   Choose slender green beans without swollen seeds. Thick beans remain coarse even when cut finely, while a tender bean keeps the clean bite this garnish requires.
3. 3

   Blanch the garnish

   Bring the water and salt to a lively boil in a small saucepan. Add the bean lozenges and cook for 1½ to 2 minutes, until vividly green and tender with a slight bite. Lift them into cold water, then blanch fresh peas for 30 to 45 seconds, or frozen peas for about 20 seconds, and cool them the same way. Drain both very well. If the vegetables have gone only slightly too tender, chill them at once and reserve them for the bowls rather than warming them again. If they have collapsed, blanch a fresh tablespoon. Ça se rattrape, and with a garnish this small the honest rescue costs almost nothing.

4. 4

   Warm without boiling

   Empty and dry the saucepan, add the prepared Potage Fontange, and warm it over medium-low heat, stirring along the bottom and around the corners. It should become glossy and fluid without bubbling. If it has tightened while standing, whisk in hot water one tablespoon at a time until it falls from the ladle in a smooth ribbon. If overheating makes it look grainy, remove it from the heat and blend briefly or pass it through a fine sieve. Do not keep boiling in the hope that it will smooth itself; it won't.

5. 5

   Finish as Marigny

   When the soup is fully hot and correctly seasoned, fold in the drained peas and green-bean lozenges. Warm them for no more than 30 seconds, just long enough to take off the chill, then ladle the Potage Marigny into warmed soup plates. Each serving should show several whole peas and clean green lozenges against the silken base. Serve immediately. À table!

Chef Tips

• •Potage Fontange is the foundation, not an ingredient to improvise around. Bring it to this recipe fully finished according to its own entry; Marigny changes only the garnish.
• •Frozen peas are the honest choice outside pea season. They are picked young and hold their sweetness and colour better than tired pods that have spent days traveling.
• •A lozenge is a small diamond cut on the diagonal. The shape is not plating theater: it shortens the bean fibres and gives the spoon a tender, distinct bite.
• •Warm the soup plates before serving, but keep them merely warm. Fierce heat continues cooking the tiny garnish and steals the freshness you worked to preserve.

Advance Preparation

• •Prepare the Potage Fontange according to its own entry up to one day ahead, cool it promptly, cover, and refrigerate. Reheat it gently while stirring; loosen only if it has tightened in the cold.
• •The peas and bean lozenges may be blanched up to four hours ahead. Cool, drain, and refrigerate them separately from the soup, then add them only at the final warming.
• •Once assembled, Potage Marigny is best served at once. Leftovers may be chilled promptly and kept for up to two days, though the garnish will gradually lose its distinct bite.
