1,000-3,000 Scovilles. The Cascabel Chile is grown in several areas of Mexico. It is small and round, 2-3 cm in diameter, and matures to a deep red.It is also called Chile Bola, meaning ball chile in Spanish. When dried, it turns to a dark brownish red, and the seeds become loose and rattle inside the chile. This is the reason for the name Cascabel, which means little bell or sleigh bell in Spanish.With a mild to moderate heat level, the Cascabel is perfect for adding a touch of heat to soups, salsas, stews and sauces.
