In my search for waffle/pancake recipes, I found The Daily Dietribe. The guide for creating your own mix was SUPER helpful. She gives you tips on how much and what kinds of gluten-free flours and starches work best for different textures, as well as tips for adding herbs and spices, puréed fruit and other ingredients for a unique mix whether you're going for sweet or savory. She also explains how you can omit the egg as well. She has updated the guide because apparently the measurements were not accurate. For my batch, I think they worked out just fine! I did notice my batter was pretty thin, but the end result was a light, fluffy texture.
