Ingredients

Equipment Needed

• •Wide 4-quart nonreactive saucepan
• •Fine-mesh sieve
• •Clean lint-free linen kitchen towel
• •Cheesecloth or fine filtering cloth
• •Instant-read thermometer
• •Two large bowls for ice baths
• •Wire cooling rack and rimmed tray
• •8-inch (20 cm) shallow square glass serving dish
• •Low tray for crushed ice

Instructions

1. 1

   Build the court-bouillon

   Combine the cold water, white wine, leek, carrot, onion, parsley stems, tarragon sprigs, bay leaf, peppercorns, and salt in a wide nonreactive saucepan. Bring it slowly to a simmer, then hold it at a quiet tremble for 20 minutes so the wine loses its raw edge and the vegetables give the liquor their sweetness. A violent boil drives away the wine before it has seasoned the broth.

2. 2

   Poach and chill

   Lower the frog-leg pairs into the court-bouillon and adjust the heat so the liquid barely trembles. Poach for 4 to 7 minutes, depending on size, until the flesh is opaque, gently firm, and reaches 145°F (63°C) at the thickest part. Lift the legs onto a rack set over a chilled tray and refrigerate promptly until completely cold. Strain and reserve the poaching liquor. When the legs are cold, trim away loose cartilage or ragged tissue without separating the joined pairs, then press them carefully in a clean lint-free linen towel until every surface is dry.

3. 3

   Clarify the liquor

   Measure 3 cups (720 ml) of strained poaching liquor into a clean saucepan, reducing it first if you have more. Cool it completely over an ice bath, then whisk in two egg whites. Heat very slowly, stirring until pale curds begin to rise; once they form a raft across the surface, stop stirring, open a small hole in the raft, and maintain the gentlest simmer for 10 minutes. Ladle the clear liquor through a damp, fine cloth without pressing the solids. If it remains cloudy, cool it again and repeat the clarification with the remaining egg white. Ça se rattrape. Reserve 2 cups (480 ml) of clear court-bouillon for the jelly.

4. 4

   Make the chaud-froid

   Sprinkle the smaller measure of gelatin over its 2 tablespoons of cold water and leave it to bloom for 5 minutes. Melt the butter over medium-low heat, whisk in the flour, and cook this roux for 2 minutes without letting it brown. Stir in the paprika for 10 seconds, then whisk in the fish stock gradually so no lumps form. Simmer gently for 8 to 10 minutes, add the cream, and continue until the sauce is smooth, glossy, and thick enough to nap the back of a spoon. Remove it from the heat, whisk in the bloomed gelatin, season with salt and white pepper, and pass it through a fine sieve.

5. 5

   Coat each nymph

   Set the bowl of chaud-froid over an ice bath and stir until the sauce is cool but still fluid, about the texture of thick cream. Holding each cold, dry pair by the bone ends, lower it into the sauce one after another, let the excess fall back into the bowl, and place it on a rack to set. Chill the coated legs for 20 minutes. If the coating slides off, either the legs are damp or the sauce is too warm: blot the legs again, chill the sauce for a few minutes, and repeat. If the sauce sets in the bowl, stand it briefly in lukewarm water and stir until supple. Ça se rattrape.

6. 6

   Mix the Champagne jelly

   Sprinkle the larger measure of gelatin over its ¼ cup of cold water and leave it for 5 minutes. Warm 1 cup (240 ml) of clarified court-bouillon until hot but not boiling, remove it from the heat, and dissolve the bloomed gelatin in it completely. Stir in the remaining clarified court-bouillon, then the chilled Champagne. Skim away any foam and let the jelly mixture cool until it is no warmer than the room and remains freely pourable. Once the Champagne is added, do not boil it. If the jelly begins setting in the pitcher, stand the pitcher in lukewarm water and stir gently.

7. 7

   Cast the clear base

   Pour about ¾ cup (180 ml) of Champagne jelly into a shallow 8-inch (20 cm) square glass serving dish. Refrigerate for 30 to 45 minutes, until completely set and firm enough to support the coated legs. This first layer is not decoration alone; it keeps the nymphs suspended rather than stranded against the bottom.

8. 8

   Plant the water-grasses

   Arrange the coated frog-leg pairs neatly over the set base, leaving small channels of clear jelly visible between them. Lay the chervil pluches and tarragon leaves between the pairs in loose strands like water-grasses. Spoon over just enough liquid jelly to anchor the legs and herbs, about ½ cup (120 ml), then chill for 15 to 20 minutes. Once anchored, pour the remaining jelly slowly down the side of the dish until the legs are covered by about ¼ inch (6 mm). If anything floats, lift it out before the jelly sets, return it to the base, and anchor it with two spoonfuls at a time before continuing.

9. 9

   Set and serve

   Refrigerate the finished dish for at least 4 hours, preferably overnight, until the Champagne jelly is clear and softly firm. Set the glass dish in a low tray of fresh crushed ice just before serving. This replaces the carved ice block honestly: the nymphs remain properly cold, while the jelly supplies all the spectacle needed. Keep the dish over ice and return any remainder to the refrigerator promptly. À table!

Chef Tips

• •Good frozen frog legs are an honest choice and often better than tired fresh ones. Thaw them overnight in the refrigerator, keep them cold, and choose joined pairs of similar size so they poach at the same rate.
• •Use sweet, unsmoked paprika. The target is sunrise gold, not brick red, and smoked paprika changes the character of the fish chaud-froid entirely.
• •Choose a dry, non-vintage brut Champagne with clean acidity. The jelly needs freshness rather than grandeur, and the rest of the bottle belongs at the table.
• •Chervil pluches are the fine picked shreds of chervil named by the old kitchen vocabulary. Their delicate shape makes the water-grass illusion; parsley is sturdier, darker, and not the same thing.
• •Keep the finished dish at or below 40°F (4°C) and serve it within 24 hours of assembly. Cold jelly protects the arrangement, not the cook, so the poached legs must remain properly refrigerated.

Advance Preparation

• •The frog legs may be poached, chilled, trimmed, and dried up to 8 hours before coating. Keep them covered and refrigerated, then blot them once more before they enter the chaud-froid.
• •The court-bouillon can be clarified a day ahead. Chill it promptly in a covered container, then measure and warm only what is needed to dissolve the jelly gelatin.
• •Assemble the complete dish the evening before serving. Once the top has set, cover the dish without touching the jelly and refrigerate overnight. Do not freeze it, since freezing clouds the gelée and makes it weep.
