- 2 cups freshly squeezed tangerine juice
- 2 tangerines
- 1 tablespoon coarsely chopped fresh tarragon leaves
- 1 egg yolk
- Salt and freshly ground black pepper
- 1 cup pure olive oil, plus more for tossing with and brushing on asparagus
- 2 large bunches asparagus, about 2 pounds total, trimmed and cooked for 2 minutes in boiling salted water, then cooled
- Long curls tangerine zest, fresh or candied
- Coarsely chopped toasted hazelnuts or pine nuts, optional
Put the tangerine juice in a small non-reactive saucepan and bring to a boil. Cook until reduced to 1/2 cup. Let cool to room temperature.
Combine the reduced juice, tarragon, egg yolk, and salt and pepper, to taste, in a blender and blend until well mixed. With the machine running, add the 1 cup olive oil, at first by drops and then, as mixture emulsifies, in a thin, steady stream until all the oil is incorporated. Taste, for seasoning. Scrape into a jar, cover, and refrigerate until needed. You should have about 1 2/3 cups mayonnaise. Keeps 2 to 3 days, refrigerated.
Prepare the grill and let burn down to medium coals. Toss the cooled asparagus with about 1 tablespoon olive oil and season with salt and pepper. Grill over medium to low coals, turning the spears as needed, until they take on a little color and are just tender, about 6 minutes. Cover the grill, if necessary, to maintain the heat.
Arrange the asparagus on a platter with the reserved tangerine segments. Dot with the mayonnaise, and drizzle with any tangerine juice left in the bowl. Garnish with fresh or candied zest and the nuts, if using. Serve at once.
Cook's Note: Every cook has insecurities. One of mine is mayonnaise. I always get a little anxious until I see it coming together in the blender. If the mayonnaise is too thick, thin it, with the machine running, by pulsing in a little cool water. If you are concerned about raw eggs, use a pasteurized egg product or an egg substitute such as Egg Beaters.
* Raw Egg Warning
Food Network Kitchens suggest caution in consuming raw and lightly cooked eggs due to the slight risk of salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly refrigerated, clean grade A or AA eggs with intact shells, and avoid contact between the yolks or whites and the shell. For recipes that call for eggs that are raw or undercooked when the dish is served, use shell eggs that have been treated to destroy salmonella, by pasteurization or another approved method.
