I've used it mixed with ground beef to make hamburgers. If I grill them I also baste them with maple syrup.
Here is a recipe I tried recently that turned out prettykinda OK! I may have posted before but what the hey.
Maple Syrup Marinade
from http://southernfood.about.com/od/bakedchicken/r/bl80312i.htm
salt and pepper
1/2 cup maple syrup
2 tablespoons chili sauce
2 tablespoons ketchup
2 to 3 tablespoons lemon juice
2 tablespoons grated onion
1 1/2 teaspoon Worcestershire sauce
1/2 teaspoon salt
1/2 teaspoon dry mustard
1/4 teaspoon black pepper
(Note from Cap'n Obvious: Works for about 8-10 pieces of meat. Since I was making quite a bit more I used more marinade.)
I didn't have any chili sauce so I increased the ketchup and also the maple syrup to about double the amount and added >a litte< chili powder because Mrs 6 and youngest son aren't hot food fans.
The Maple Syrup Marinade then worked for several hours (refrigerated) on chicken legs and thighs. Some were grilled outside and some oven cooked.
Both were great but I would have preferred a little more "kick."
One thing I noticed though. The chicken was great right off the grill or out of the oven BUT a couple of days later I took leftovers and nuked them at work. NOT THE SAME - not even close!
ooohhhh, that sounds great!!
