Preheat and Prepare. Preheat the oven to 275°F/135°C. Let the ham come to room temperature and remove it from its packaging. If the ham has a plastic disc remove and discard it. Place ham cut side down in a 13x9-inch baking pan. Pour pineapple juice into the pan around the ham.
1 Bone-In Smoked Spiral Cut Ham, ½ Cup Pineapple Juice
Heat in Oven. Cover ham with aluminum foil and crimp the edges around and under the pan. Put the ham in the oven and heat it for approximately 1½ hours. Use an instant-read meat thermometer to check the internal temperature of the ham, which should be 135°F/57°C.
Make Glaze. While the ham heats, make the glaze. In a small saucepan mix the dark brown sugar, bourbon whiskey, honey, Dijon mustard, and ground allspice. Bring to a boil and let simmer over medium heat for 8 to 10 minutes. Let cool. Taste and, if needed, add the lemon juice to make it less sweet and brighten the flavor.
1 ¼ Cups Dark Brown Sugar, ⅓ Cup Bourbon Whiskey, ⅓ Cup Honey, 2 Tablespoons Dijon Mustard, ¼ Teaspoon Ground Allspice, 1 Teaspoon Lemon Juice
Glaze Ham. During the last 30 minutes of heating increase the oven temperature to 425°F/218°C. Remove the ham from the oven, uncover it, and spoon and brush the surface of the ham with the glaze. Return the ham to the oven to let the glaze set.Watch the glaze carefully, so that it does not burn.
Serve and Enjoy. Serve the baked ham with some of the slices fanned out and with any unused remaining glaze on the side.
Notes
My Top Tip♡ The spiral ham you choose makes a big difference in the look and taste of your glazed ham. Most grocery stores have their own branded hams that are generally more economical than major brands.Target's Market Pantry ham is very delicious and has been my favorite for a few years. I've also used Walmart's and Aldi's smoked ham, which are also delicious but they don't look as quite as pretty after it has been heated and glazed.Make-Ahead & StorageMake-Ahead: A smoked baked ham is generally not made in advance, since it is already cooked and you are only heating and glazing the ham.Storage: You can keep leftovers in an airtight container or a resealable plastic bag in the refrigerator for up to a week and frozen for up to a month.Using Leftovers: Leftover glazed ham is delicious and can be used in cold or hot sandwiches and casseroles. Don't discard the leftover bone or any of the small bits and pieces of ham! Those are perfect for making Lima Beans and Ham and also to flavor Bean Soup and Split Pea Soup.
