How to Make It
Combine the sugar, salt, peppercorns, jalapeño and star anise in a medium bowl and mix well. Add the orange juice, vodka, olive oil, soy sauce, ginger and mint sprigs and stir well. Pour into a glass or ceramic loaf pan or another pan or dish that would hold the beef snugly.
Add the beef to the loaf pan and turn it several times, rubbing the curing mixture into the meat; the beef should be buried in the curing mixture. Cover the beef with plastic wrap and weight it with a 28-ounce can or another heavy weight. Refrigerate for 6 to 8 hours.
Remove the beef from the pan. Brush off the curing mixture and pat dry with paper towels. Wrap the tenderloin in plastic wrap and freeze for about 30 minutes, or until partially frozen. (This will make the meat easier to slice.)
