1. 1/2 cup ketchup
2. 2 tablespoons vinegar
3. 2 tablespoons brown sugar
4. 4 tablespoons Worcestershire sauce
1. Combine all ingredients.
2. Completely cover meat in sauce.
3. Place under broiler 5 to 10 minutes (may also be done in oven).
I plan on doing some experimentation eventually with this sauce and different kinds of meat. I wouldn't recommend changing it at all for ham though; the flavours are in absolute perfect harmony. I liked it on beef too, but I only had a little, and I haven't tried it on any poultry or lamb or anything. This is simple enough to build off of plenty if one wishes, and I'd love to see any new ideas in comments if people have them.
