Serves 6 to 8.

1 (2 pound) boneless pork loin roast
3/4 cup barbecue sauce
1/3 cup orange marmalade
1/2 teaspoon hot pepper sauce
1/2 teaspoon grated horseradish (optional)

Season roast with salt and pepper; place over indirect heat on medium-hot grill.

Stir together remaining ingredients and baste roast every 8 to 10 minutes with mixture, until roast is done (internal temperature measured with the meat thermometer is 155-160F), about 30 to 45 minutes.

Let roast rest for 5 to 8 minutes before slicing to serve. Discard any leftover basting mixture.
