Step 1

Remove the skin and most of the excess fat. Leave a layer of fat, though, to render while the ham bakes.

Step 2

Score ham in a diamond pattern. This looks nice but also allows the fat to render while cooking.

Step 3

Place scored ham in a roasting pan.

Step 4

Bake at 325 for 20 minutes per pound until the internal temperature is 160.

Step 5

While ham is baking make the glaze. Mix mustard, brown sugar, honey, and cinnamon together.

Step 6

During the last 45 minutes of cooking spread glaze over ham.

Step 7

Let ham rest.

Step 8

Slice into thin slices.
