Homemade waffle batter may take longer to cook than packaged pancake and waffle mix. The packaged mix waffles are done in about 5 minutes. Made from scratch recipes take a few minutes more.
The Belgian waffle grid holds more batter than a traditional grid. These recipes give a range of batter to use, for example, 2/3 to 3/4 cup. The larger amount should be used for a Belgian waffle grid.
Waffles can be frozen and then reheated. Make a large batch ahead of time and let cool on a cooling rack. Freeze in airtight storage bags then heat in an oven or microwave.
