Notes
Make the waffle batter up to one day in advance and whisk well before using. Top hot waffles with 1 cup fresh or thawed blueberries, strawberries, or bananas for an extra treat.From Paula Altenbach: "To avoid an overly sweet waffle, I used Amish Friendship batter that had been fed a day earlier and allowed to consume some of the sugars. These came out of the Belgium waffle iron steamy and tender without being overly sweet. We dropped them in a toaster to keep the crowd fed at their own pace."This recipe is courtesy Suzy at Kitchen Bouquet.
