Updated almond flour waffles recipe.

This is where it's ended up, after about four years of experimentation:

1 cup almond flour
1 pinch salt
1 teaspoon baking soda
3 eggs
¼ cup sour cream or yogurt
¼ cup sugar or other sweetener
¼ cup regular flour
1 to 2 teaspoons vanilla extract, to taste, or another flavoring like almond extract.
⅓ cup neutral oil or coconut oil

Makes about 4-5 waffles. The 1/4 cup of regular flour is really just to bring everything together if that makes sense, but you can just use 1-1/4th to 1-1/2 cups almond flour and maybe put in a pinch or two of Xanthan gum if you want to make these gluten free.
