dried red chiles Known in Thai as prik haeng, dried red chiles are dried cayennes. They are a versatile pantry item for preparation of Chinese, Thai, and Indian dishes especially. They add a smoky hot flavor to many dishes. Dark-red dried red chiles are available at Southeast and South Asian groceries, usually in small cellophane bags. They keep almost indefinitely.
You can substitute one teaspoon of dried chile pepper flakes for each dried pepper called for.
