"For cooking, a hole is poked in the pepper beforehand to keep expanding hot air from bursting the pepper. It may be skewered then broiled (grilled), or pan-fried in oil, stewed in a soy sauce- and dashi-based liquid, or simply eaten raw in a salad or as a condiment. It is thin-skinned and will blister and char easily compared with thicker-skinned varieties of peppers."
