The pasilla chile (/ˌpɑːˈsiːjə/ pah-SEE-yuh) or chile negro is the dried form of the chilaca chili pepper, a long and narrow member of species Capsicum annuum. Named for its dark, wrinkled skin (literally "little raisin"), it is a mild to hot, rich-flavored chile. As dried, it is generally 6 to 8 inches (15 to 20 cm) long and 1 to 1+1⁄2 inches (2.5 to 3.8 cm) in diameter. The fresh narrow chilaca can measure up to 9 inches (230 mm) long and often has a twisted shape, which is seldom apparent after drying. It turns from dark green to dark brown when fully mature.
