You will need a canned cooked ham in a metal can. Take key off and put in a safe place. Take a juice can opener and punch holes all around the top of can. Bake in the oven at 325 degrees F for 1/2 hour. Pour all liquid out. Then pour in sauce.

SAUCE:

1/4 c. corn syrup
4 tbsp. brown sugar, firmly packed
1 tsp. cinnamon

Then bake in oven for 1 hour. (It might overflow, so put a cookie sheet or foil under the can.) Remove and open with the key.
