The Chilhuacle Amarillo is a rare, mild yellow chili pepper from the Oaxaca region of Mexico, part of the Capsicum annuum family and one of the three main chilhuacle varieties alongside Chilhuacle Negro (black) and Chilhuacle Rojo (red). It is essential for making mole amarillo, the traditional yellow mole sauce of Oaxaca.  This pepper is one of the rarest and most expensive chiles in Mexico. Its scarcity and cultural importance mean it is highly sought after by chefs and home cooks aiming for authentic Oaxacan flavors.
