Beat 1 egg until you can't beat it anymore.Add the HUGE overflowing spoon of almond butter into the egg and carefully mix.Stir in the almond flour, salt, and then the baking powder.HEAT the waffle iron on medium to medium high and grease the top and bottom with butter.Add the baking soda and lemon juice to the batter and mix to combine.Pour batter into the iron and cook until desired crispness. Sometimes I re-butter midway for extra crispies.Enjoy immediately.
