I have a friend who makes whole-grain pancakes and adds whatever he has leftover in the fridge. Chopped green onion and fresh cooked sweet corn, cut off the cob, is one of his favorite variations, but he's used things like chopped apples, mashed sweet potatoes, grated zucchini and the like.
Sometimes he puts lemon curd or assorted preserves on the pancakes. Other times, he rolls the pancake around a sausage and eats it like a little sandwich. When he uses maple syrup, he likes to buy the grade B stuff, as he prefers the flavor. I think it's darker and richer.
