Rigatoni are tube pasta with ridges. Eden's is a potent U.S.A. organic blend of 70% whole grain kamut and 30% whole grain buckwheat. Remarkably delicious, quick, 100% whole grain pasta. Many sensitive to modern wheat still enjoy Khorasan or kamut wheat. Buckwheat does not contain gluten. It is the best source of the important flavonoid, rutin. Crafted at the Eden Organic Pasta Company on vintage Italian equipment with brass dies and slowly air dried. Rich in thiamin B1, magnesium, and zinc, and a good source of protein, fiber, iron, and niacin B3. Enjoy with vegetables, sauces, or in stroganoffs, soups and salads. Packaged in a reclosable, recycled and recyclable box with a tasty recipe and its photo on the back.
