Rinse and drain fermented black beans.
Cut stems and seeds from chiles (leave some seeds in if you want it spicier).
Mince chiles in a food processor.
In a bowl, smoothly blend cornstarch with 1/2 cup chicken broth; then blend with remaining broth and the ketchup.
Stir in beans and chiles.
*Salted fermented black beans contribute a complex pungency; find them Asian markets and online; or use 1/2 cup soy sauce.
