Preparing Dried Chiles for Mexican Cooking: How to Grind Them
How to grind dried chiles into powder: clean, toast until fragrant, cool, grind and store airtight. Also covers when to rehydrate chiles instead.
Contents
The short answer
To grind dried chiles, toast them in a pan until they change color and smell toasted. Let them cool, then grind them to a powder and store it in an airtight container. Grinding works on chiles that are still dry. Soaking chiles in water is a separate technique, used when a recipe needs soft chiles that can be blended rather than a dry powder.
Step by step: turning dried chiles into powder
- 1. Clean the chiles. Remove the stems and seeds. Mexican recipes that use dried chiles such as ancho commonly list them with stems and seeds removed.
- 2. Toast them in a pan. Heat the chiles until they change color and smell toasted. These two cues tell you the chiles are ready.
- 3. Let them cool. Allow the toasted chiles to cool before grinding.
- 4. Grind to a powder. Grind the cooled chiles until they become a powder.
- 5. Store airtight. Keep the ground chile in an airtight container.
Gaps in the available guidance
The guidance reviewed for this article leaves several details open. It does not give a pan temperature or an exact toasting time. It does not say whether to remove stems and seeds before or after toasting, or what kind of grinder to use. It also does not say how long the powder keeps in storage. Judge toasting by the color change and aroma rather than by the clock, and follow your grinder's instructions for dry spices.
Do you need to rehydrate dried chiles first?
No, not for grinding. The toast, cool and grind method uses dry chiles and has no soaking step. Rehydrating is for recipes that need softened chiles, such as sauces or salsas where the chiles are blended with liquid. Rehydrating is also different from drying fresh peppers: it restores moisture to chiles that have already been dried.
How to rehydrate dried chiles when a recipe calls for it
- 1. Place the chiles in an oven-safe bowl.
- 2. Pour boiling water over them, using just enough to cover the chiles.
- 3. Cover the bowl and let the chiles sit for 15 to 30. The available source excerpt is cut off before the time unit and any doneness cue, so confirm the soaking time in the full recipe you are following.
Dried chiles you'll see in Mexican recipes
Two dried chiles in the reviewed material are ancho and chile de árbol (literally "tree chile"). One Mexican recipe lists 6 large tomatillos, peeled and washed, with 4 ancho chiles, stems and seeds removed. The same recipe calls for 12 to 24 chiles de árbol, depending on how much heat you want, so árbol is the chile used to adjust the spice level there. The reviewed sources do not include a full chart of Mexican dried chiles or describe their individual flavor and heat. Use a dedicated chile reference if you need to compare varieties.
