Nearly every spice or dried chile that is sold ground in jars in the supermarket can be purchased in whole form as well. While there’s no denying the convenience of preground spices, sometimes you end up paying for semi-flavorful dust.
You get far more intense flavor for your dollars if you toast and grind whole spices before adding them to a dish.

Since the flavors and aromas of spices and chiles are volatile, they can vanish from preground versions long before you buy the jar. Toasting and grinding whole spices releases these volatile compounds, along with their essential oils, exactly when you need them for a dish, not before. Plus, toasting triggers browning and caramelization of the spices’ proteins and sugars for even more flavor.
Whereas blooming spices involves cooking ground spices in fat to help reawaken their flavors, with this technique spices are toasted whole in a dry pan, without any fat. Since it’s often the first step in a recipe, the toasting can be done in a Dutch oven or whatever vessel you’re already using rather than pulling out a separate skillet.
To gain the full benefit, spices only need to be toasted until they become fragrant, usually 1 to 3 minutes.
Toast them in the pan over medium heat, shaking the pan occasionally to prevent scorching. Remove the toasted spices from the pan right away to prevent burning. For chiles (whether left whole or torn into smaller pieces), the toasting time is a bit longer, typically 2 to 6 minutes.
We suggest having a dedicated spice grinder; an inexpensive blade-type electric coffee grinder is a good choice. For everyday cleaning, simply wipe out the interior with a damp cloth. For a more thorough “dry cleaning,” which is smart especially after grinding chiles, add a few tablespoons of raw white rice to the grinder and pulverize to a fine powder, about 1 minute. The rice powder will absorb the oil and residues left behind; then you can wipe it out with a damp cloth.
Or, as an alternative to an electric grinder, a large mortar and pestle with a rough interior and long, heavy pestle is fun to use and makes grinding spices and chiles by hand a breeze. This piece of equipment is also easy to clean.
Follow these simple steps for toasting and grinding whole spices at home.
Place spices in dry skillet or pot over medium heat, stirring frequently to prevent scorching, until you can smell aromas.
Immediately transfer to small bowl to prevent burning. Let cool, then process in spice grinder until finely ground.
Whether you use a skillet, pot, or oven, it's easy to toast whole chiles, too. Here's how.
Place chiles (either stemmed, seeded, and torn or left whole) in dry skillet or pot over medium heat, stirring frequently, until fragrant, lowering heat if chiles begin to smoke.
Alternatively, arrange chiles (either stemmed, seeded, and torn or left whole) on baking sheet and toast in 350-degree oven until just fragrant and puffed.
