How to make Peppercorn Roasted Pork with Vermouth Pan Sauce

Grind 40g pink peppercorns with black peppercorns and fennel seeds in grinder, then stir together with garlic, oil, and 1 tablespoon salt.

Pat pork dry and use a paring knife to make about 16 (1-inch-deep) slits all over roast. Stuff slits with all but 1 tablespoon garlic-peppercorn paste, then rub remaining tablespoon all over roast. Put in a small (13-by 9-inch) flameproof roasting pan and marinate, chilled, 8 to 24 hours.

Let pork stand at room temperature 1 hour. Preheat oven to 177°C with rack in middle.

Roast pork, fat side up, until an instant-read thermometer inserted into centre of meat registers 66°C, 1 1/2 to 2 hours. Transfer pork to a cutting board and let rest 30 minutes.

Meanwhile, pour off all but about 1 tablespoon fat from roasting pan. Add vermouth to pan and boil, scraping up brown bits, 2 minutes. Stir in broth, any meat juices from cutting board, and remaining 2 tablespoons pink peppercorns and boil until reduced to about 190g , about 5 minutes.

Knead together butter and flour, then whisk into sauce and boil, whisking constantly, until just slightly thickened, about 2 minutes.

Serve pork with sauce.
