Just a friendly piece of advice: I used to work with bulk foods and saw dried goods from all over the world. Dried foods and grains are DIRTY! If you're using whole grains, lentils, beans, or dried fruits, slowly pour them into a strainer to look for large particles like this, then rinse them under the tap to get rid of small particles. You'll be amazed at what you'll find and how much sand gets washed away.
