It's a bit daunting to start baking without the most common ingredient , flour. I looked for recipes with the least amount of ingredients and started there. It was a little less overwhelming that way and my initial shopping trip wasn't very hefty. After testing a few recipes you'll get an idea of what taste good to you and what you might want to try and tweak. It was a little investment to start mostly becuase I don't stock many gluten free ingredients in my regular pantry at home, but for about $15 you'll have enough ingredients to play around with several recipes.
My new must have gluten free ingredients are:
Sweet Rice Flour
