Spices, like practically all foods, come in a full range of quality. For the best spices possible, finding a specialty grocer or spice store in your area could give you the most flavorful choices. Another good option is to purchase spices online, from vendors like Épices de Cru, a long-time Zingerman’s partner, at Spicetrekkers.com. The next best choice is to use recently purchased spices. Spices lose their aroma and flavor over time, so newly purchased spices will be much better than the jar that’s been open in your cupboard for a year. If you open up your jar of ground cinnamon and it doesn’t smell like much, it’s time for a new one.
