Preheat oven to 400°F. Add rice and beans to Kitchen Mill, and grind into flour; set aside. Add ½ cup water, honey, and yeast to WildSide jar and secure lid. Press "Pulse" 2 times. Allow yeast to proof for 5–10 minutes. Add salt, vinegar, oil, 1¼ cup water, and eggs to jar and secure lid. Pulse 2–3 times. In large bowl, combine flours, powdered milk, and xanthan gum. Add ⅓ of flour mixture to WildSide jar, secure lid, and pulse 2–3 times. Add another ⅓ of flour mixture, secure lid, and pulse 3–5 times. Add final ⅓ of flour mixture, secure lid, and pulse 8–10 times or until ingredients are incorporated and dough ball forms. Allow dough to rest in jar with lid on until dough doubles in size. Dump dough ball onto oiled surface and shape loaf. Place loaf, seam side down, in greased loaf pan. Allow dough to rise in warm place until dough has topped pan by approximately 1". Bake for 10 minutes. Place foil over loaf, and bake for 50 more minutes.
