Fresh vs. Dried Chiles: Knowing the Difference
The heat level in a chile is not just about the capsaicin; it is about how the moisture content dictates the release of flavor. Fresh peppers are immediate and sharp, while dried pods act like spices, needing heat or liquid to wake them up.
Mind your hands and your air
Capsaicin is an oil that stays on your skin and lingers in the air when toasted. Always wash hands thoroughly after handling, and ensure the kitchen is ventilated when working with dried varieties in a hot pan.

Awakening Dried Pods
Before soaking, drop dried chiles into a dry, hot skillet for 30 seconds per side until they become fragrant and pliable. This brief heat releases the natural oils that have gone dormant during the drying process.
The method.
Select for the dish
Choose fresh chiles for raw salsas or final garnishes. Choose dried chiles for slow-cooked braises, moles, or soups.
Prepare fresh
Remove the seeds and veins if you want less heat, then dice small to ensure an even distribution of heat throughout the meal.
Prepare dried
Wipe away surface dust. Remove stems and seeds. Toast in a dry pan until fragrant, then submerge in hot water for 15 to 20 minutes until soft.
Integrate
Puree the softened dried chiles with the soaking liquid for a base, or slice the toasted pods thinly to stir into a spice rub.
Other turns to take.
The Smoked Path
Use chipotles, which are dried, smoked jalapeños, to bridge the gap between fresh vegetal heat and the deep smoke of a dried chile.
When it doesn't go to plan.
If you accidentally use too much heat in a dish, adding a small amount of fat or an acidic element like lime juice can help round out the sharp edges.
When soaking dried chiles, do not use boiling water for too long or the liquid can turn bitter; a gentle soak in just-off-the-boil water is sufficient.
Store dried chiles in a cool, dark cupboard in an airtight container to maintain their oils for up to six months.

Can I swap fresh for dried in a recipe?
Not directly. Dried chiles have a condensed, sweet, or smoky flavor that fresh ones lack. If you must swap, use a pinch of red pepper flakes for heat, but acknowledge that you will lose the body and nuance of the dried pepper.
How do I know if a dried chile is past its prime?
If it snaps like a dry twig or shows signs of gray mold, discard it. A good dried chile should be leathery and slightly flexible.
