Pork needs a little lighter treatment. Substitute a white wine for the Burgundy in the basic beef marinade and try that. Also, pork is very agreeable to mustard. Try adding some honey mustard to the recipe. Chicken and other poultry go well with fruit flavoring.
Pineapple chicken is on everyone's list of favorite things.
Add a cup of pineapple juice to your basic chicken marinade. Or you could try orange juice or cranberry juice. If you are going to use juice, use frozen concentrate, thawed. It's three times as strong as the fresh squoze stuff and just as good. I haven't tried it, but I bet fish marinated in non-alcoholic Margarita mix would be very good.
