Makes about 2 dozen bars.
Note: From Judy Malmon, baker-owner of Cooqi in St. Paul. Malmon sells a ready-made gluten-free flour mix in her store. "If you can't get to us, you can use any commercially available gluten-free flour mix, but make sure that it contains xanthan gum," she said. "If it doesn't, add 3/4 teaspoon xanthan gum to 1 2/3 cup flour mix." Her easy-to-make flour mix formula, below, yields 3 cups, of which 1 2/3 cups gets used in the recipe. Malmon also recommends McCann's Irish Oats (available in most supermarkets), which are grown and processed separately from wheat crops; for those concerned with using oats, Malmon suggests substituting 1 cup quinoa flakes.
For flour mix
