Linda, you left out a key part of the meat loaf, th topping :-)
I like to use a very simple recipe:
Vinegar
Ketchup
Brown sugar
I don't have the specificis on how much to use, but that doesn't really matter. Just dump about a cup of vinegar in a bowl, add a bunch of ketchup until it thickens up to a consistency you like, and then sweeten with brown sugar to taste. I like to coat the meat loaf with this for the last 20-30 minutes of the bake time (uncovered so that it browns).
