Buying grains like oats, quinoa and millet from the bulk bins is a great way to buy good-for-you, whole foods for the best price. One problem when you get these whole grains home and store them in a glass Mason jar or other container is that there are no instructions for cooking, and no information about how much water to use.

This infographic can help with that, and it would be ideal to print out and tape to the inside of the cabinet door where your store your grains.

Keep this on hand, and you'll never have to pull out your smartphone or hop on your laptop to find out how much water is needed to cook your couscous. Once you have the right grain-to-water ratio, the general rule of thumb for cooking grains is to bring the water to a boil, add the grains, return to a boil (except for couscous, which comes off the stove at this point) and then reduce the heat to a simmer, cover and cook until the grains reach desired consistency.
