1,000-3,000 Scovilles. Capsicum Annuum. 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.
