For this slightly sweet, subtly nutty Hearty Wheat Bread with Flax Seed, our Test Kitchen found that a blender, rather than a food processor, was the best choice for grinding the flax seed. Look for flax seed in health food stores.
Place the flax seed in a blender container. Cover and blend until ground. Add the ingredients to a 1-1/2- or 2-pound bread machine according to the manufacturer's directions, adding the ground flax seed with the flour. If available, select the whole grain cycle, or select the basic white bread cycle. Select desired color setting.
