Typical preparation is: remove stems and seeds as desired, rehydrate the dried chiles by soaking or simmering until soft, then pulverize, mash, or puree them into a paste. Listings also note they can be used rehydrated or ground into powder.
Net weights in the results range from small spice-size containers (about 2–2.5 ounces) up to larger retail packages such as 7-ounce and 12-ounce bags or jars.
They appear primarily as whole dried chiles (whole/dried) and as powdered or ground chile powders.
They add depth, color and warmth to sauces, soups, stews, marinades, rubs, salsas and pastes, and can be blended or incorporated into bases for stews and sauces.
