From MyRealFoodLife, this is a very good guide to baking gluten-free...http://www.myrealfoodlife.com/understan ... ee-flours/
Heavy Flours – Give structure and binding, have lower rising capacity.
Almond Flour: Weight per 1 cup:
Gives structure to a baked good that helps hold it up. It is naturally slightly sweet, and high in protein. Almond flour has some natural binding tendencies. You can make your own from grinding blanched almonds in a spice mill or coffee grinder. Buy: JKgourmet.ca (Available also at Rainbow Foods)
Coconut Flour: Weight per 1 cup:
Absorbs liquid quickly in a recipe, gives structure to baked goods. It bakes to a very slightly grainy consistency, but in combination with other flours works very well. It’s lighter than almond flour, so it is good for lighter baked goods like muffins or cakes. Has a fragrant sweet scent. Buy: TropicalTraditionsCanada.com (Available also at Rainbow Foods, Natural Food Pantry, Pantry Plus, and Bulk Barn)
Chickpea Flour (Gram/ Garbanzo Flour): Weight per 1 cup:
Absorbs liquid quickly, and is also high in protein. Has natural binding properties and gives structure to baked goods. In small amounts it can be subbed for almond or coconut flour, but you may need more sweetener to mask the slightly bean-like taste. Good for thickening gravy. Buy: contact PurestNaturalProducts.com (Available also at Rainbow Foods, Natural Food Pantry, Pantry Plus, Bulk Barn and cheapest at your local indian grocer)
Quinoa Flour: Weight per 1 cup:
Another high protein flour, Quinoa can also be partially subbed for coconut or almond. It has a fairly strong flavour, and may be best combined with other heavy flours to even it out. I personally don’t use it too often but its good if you have a nut intolerance. Buy: Bobsredmill.com (Available also at Rainbow Foods, Natural Food Pantry, Pantry Plus)
Teff Flour: Weight per 1 cup:
A lighter textured flour, Teff is darker in colour and has a pronounced flavour. It has natural binding tendencies, and can be used in small amounts to replace one of the heavier flours. Buy: PurestNaturalProducts.com or Bobsredmill.com (Available also at Rainbow Foods, Natural Food Pantry)
Buckwheat Flour Weight per 1 cup:
Results in a denser product, has natural binding tendencies. Has a lighter more neutral flavour than Teff or Quinoa. Great in cookies, pancakes, crepes and crackers. Buy: contact PurestNaturalProducts.com or Bobsredmill.com (Available also at Natural Food Pantry)
Any of those would work...
