Heat a cast-iron skillet or comal over medium, then dry toast the chiles for ~60 seconds, stirring frequently, until fragrant.
Bring a saucepan of water to boil, then turn the heat off, add the piquin chiles, cover the pot, and let them rehydrate for 10-15 minutes until soft.
Your piquin chiles are now ready to be used in various Mexican soups, sauces, and marinades.
