Nobody is indifferent to sea urchin roe: You either love it or hate it. Personally, its rich and sexy taste is my favorite flavor on earth. Until I tried the extraordinary mousse invented by Jean-Georges Vongerichten, I preferred it raw. Now I know better. The best sea urchin roe comes from southern California, and is sold in little wooden trays at Japanese markets. It is extremely fragile. It's important to use very fresh roe with a clean, ripe, rather fruity scent. Ingredients:
1/2 teaspoon unflavored gelatin (from 1 envelope) |
1/2 cup cooled vegetable broth |
1 (4-oz) tray uni (sea urchin roe) |
1 large egg yolk |
1/4 teaspoon salt |
1/2 teaspoon fresh lemon juice |
pinch of cayenne |
1/3 cup chilled heavy cream |
2 teaspoons finely grated (with a rasp) peeled fresh ginger |
2 teaspoons fresh lemon juice |
1/8 teaspoon salt |
3 tablespoons mild extra-virgin olive oil (preferably french) |
garnish: chopped chives and thinly sliced cucumber |
Directions:
1. Make mousse: Sprinkle gelatin over broth in a small saucepan and let stand 1 minute to soften, then cook over moderate heat, stirring, until dissolved, 1 to 2 minutes.
2. Force uni through a fine-mesh sieve into a bowl, scraping bottom of sieve occasionally.
3. Whisk in yolk, salt, lemon juice, and cayenne, then add broth mixture, whisking. Return to saucepan and cook over moderately low heat, stirring constantly, until it registers 170°F on thermometer, 2 to 3 minutes. (Do not let simmer or egg will curdle.) Transfer mixture to a bowl set in a larger bowl of ice and cold water. Let stand, stirring occasionally, until mixture is cold and the consistency of raw egg whites, about 10 minutes.
4. Beat cream with an electric mixer until it just holds soft peaks, then fold cream into uni mixture gently but thoroughly. Chill, covered, until set, about 1 hour.
5. Make vinaigrette while mousse chills: Press hard on ginger in a small fine-mesh sieve set over a small bowl to extract 1 teaspoon juice (discard solids), then whisk in lemon juice and salt. Add oil in a slow stream, whisking until emulsified.
6. To serve: Spoon 1/4 cup mousse onto each of 6 plates, then drizzle with some vinaigrette.
7. Cooks' notes: Mousse can be chilled up to 1 day. Ginger vinaigrette can be made 6 hours ahead and chilled, covered. Bring to room temperature before serving.
