Yep, I tried Mora's advice of adding some beer to the waffle batter. Unfortunately I didn't have enough beer to substitute half of the liquid with it -- because I bought only one can yesterday and drank most of it with the meal last night :P -- but the small amount I used today did make a difference. I didn't smell much of the beer while baking, but it made the texture fluffier (airier?) and flavor richier to make my waffles special this morning. Mmmmm..... Thanks, Mora!
My next step seems to be improving my waffle-baking skill so that both sides turn out equally brown. This waffle maker is the kind that you place on gas stove and turn over when one side is done. I LOVE it because it bakes waffles much faster than electric ones, but I guess I should bake one side a little longer than the other, and need some practice to find the perfect timing.
