Belgian Waffles remind me of late brunch at the seaside and cool autumn mornings. They should be lite, full of flavor, and have an air of carefree decadence.Traditional Belgian waffles are created with a yeast batter that sits overnight and is cooked the next morning. These are created with baking soda to shorten the waiting time. We still suggest you allow the batter to sit at least 30 minutes to allow the leavening agents to do their job.
