Grapefruit Gratin Recipes

GRAPEFRUIT SABAYON GRATIN

Steps:

• Preheat broiler.
• Cut peel, including all white pith, from grapefruit with a sharp knife. Cut segments from membranes and divide segments among gratin dishes.
• Combine yolks, sugar, and wine in a large metal bowl set over a saucepan of barely simmering water and beat with a handheld mixer at medium-high speed until mixture registers 140°F on thermometer, about 4 minutes. Continue beating over heat until mixture has tripled in volume and forms a thick ribbon when mixer is lifted, 4 to 5 minutes more. Remove bowl from heat.
• Spoon sabayon over grapefruit segments and broil 4 to 6 inches from heat just until sabayon is browned, about 30 seconds. Serve immediately.

GRAPEFRUIT AND NAVEL ORANGE GRATIN

Steps:

• Set aside 200 grams oranges and 1 grapefruit. Slice the ends off the remaining oranges and grapefruit and remove the peel and white pith by slicing down the sides from top to bottom. Holding the fruit over a bowl, cut the sections from between the membranes that separate them.
• Place a strainer over a bowl and drain the fruit. Arrange the sectioned fruit in a lightly buttered baking dish or in 6 oven-proof crème brûlée dishes. Sprinkle the fruit lightly with cinnamon.
• Pour the strained juice from the fruit into a measuring cup. Squeeze the remaining grapefruit and enough of the remaining oranges to obtain 200 grams of juice (about 3/4 cup).
• Pour the juice into a medium saucepan and add half the sugar. Cut the vanilla bean in half lengthwise and using the tip of a knife, scrape the seeds into the juice. Add the vanilla bean pod to the juice. Bring to a simmer and immediately turn off the heat, cover the pan tightly with plastic wrap, and allow the vanilla bean to steep for 15 minutes. Remove the plastic wrap.
• Fill a bowl with ice and set another bowl in it. Place a strainer over the bowl. Beat the egg yolks with the remaining sugar in a small bowl and bring the juice back to a simmer. Remove from the heat and, making sure that the juice isn't boiling, whisk half of it into the egg yolks. Whisk the tempered egg yolks into the saucepan, scraping out every last bit from the bowl with a rubber spatula.
• Place the saucepan back over medium-low heat and heat, stirring constantly with a rubber spatula or a whisk. Do not allow the liquid to come to a boil. Insert a thermometer and when the mixture reaches 180 degrees Farenheit and coats the spatula like thick cream, remove from the heat and immediately strain into the bowl set in the ice. Whisk in the crème fraiche and stir over the ice until the mixture cools. At this point, if you are not serving the gratin right away, cover and refrigerate the custard sauce.
• Preheat the broiler and place the rack about 3 inches away from the heat. Spoon the custard over the fruit. Just before serving place under the broiler and, watching closely, heat until the cream is lightly browned, 3 to 5 minutes. Remove from the heat and serve.

GRAPEFRUIT GRATIN

Steps:

• Preheat broiler with rack 4 inches from heat. Remove peel and pith from grapefruit. Halve fruit vertically; slice crosswise into 3/4-inch-thick half-moons. Place pieces, overlapping to fit, in a shallow broilerproof baking dish (ours was about 12 by 7 inches).
• In a small bowl, stir together sugar and cinnamon; sprinkle over grapefruit. Broil until sugar has begun to brown, 15 to 20 minutes. Serve with biscotti, if desired.

ROAST PORK LOIN WITH GRAPEFRUIT

Steps:

• In a roasting pan toss the onions and the garlic with the oil, add the pork loin, and season it with salt and pepper. Rub the coriander seeds over the pork and roast the pork in the middle of a preheated 350°F. oven for 1 to 1 1/4 hours, or until a meat thermometer registers 155°F. to 160°F.
• While the pork is roasting, remove 3 or 4 long strips of zest from 1 of the grapefruit with a vegetable peeler, scrape off as much of the white pith from the zest as possible, and cut enough of the zest into fine julienne strips to measure 1/4 cup. Cut away the zest, pith, and membranes from all 3 grapefruit with a serrated knife and, working over a bowl to catch the juice, cut the flesh into sections, reserving the juice. Transfer the sections to a sieve and let them drain.
• In a small heavy saucepan combine 3 tablespoons of the sugar, the zest strips, and 1/2 cup of the reserved juice, reserving the remaining juice for another use. Bring the mixture to a boil, stirring until the sugar is dissolved, and boil it until it is thickened and turns a light caramel.
• Transfer the pork to a cutting board and let it stand, covered loosely with foil, for 10 minutes. While the pork is standing, deglaze the roasting pan with the wine, boiling the mixture and scraping up the brown bits, until the wine is reduced almost completely and add the broth. Pour the deglazing mixture through a fine sieve into the pan containing zest mixture, pressing hard on the solids, and bring the gravy to a boil, stirring. Add the beurre manié, a little at a time, whisking until the gravy is smooth, simmer the gravy, whisking occasionally, for 2 minutes, and whisk in any juices that have accumulated on the cutting board. Season the gravy with salt and pepper and keep it warm.
• Arrange the grapefruit sections in a shallow baking pan or gratin dish just large enough to hold them in one layer, sprinkle them with the remaining 1 1/2 tablespoons sugar, and broil them under a preheated broiler about 2 to 3 inches from the heat for 3 to 5 minutes, or until they are just golden. Discard the string from the pork, cut the pork into 1/2-inch-thick slices, and serve it with the gravy and the grapefruit sections.
