JEALOUS DEVIL mission is to create legendary grilling fuels and experiences and there is no BBQ fuel more legendary than Binchotan lump charcoal. Binchotan's unparalleled purity, power, and performance make it the rarest and most coveted hardwood lump charcoal in the world. It was developed in 17th century Japan by master craftsmen who passed the secrets of its incredibly demanding production methods from generation to generation. Binchotan charcoal is carbonized under extreme heat (over 2,300°F) in specialized kilns for several weeks. This unique process gives Binchotan its distinctive metallic sound and whitened surface - and its incredible burn. JEALOUS DEVILcrafts its Onyx Binchotan from all-natural, ultra-dense South American hardwood and honors every step of this traditional method. Binchotan is reusable. Extinguish it with water, let it dry, and then relight it with no significant loss in structure or performance. Binchotan's uniquely hot burn produces FIR (far infrared) heat. This heat fully penetrates food for perfectly even cooking from the inside out, and seals the surface to lock in natural flavors. Binchotan's long, even, smooth burn is completely smokeless and flameless, preserving the taste of your food and providing exceptional control over flavor profiles. Pure as Heaven. Hotter than Hell.Onyx is professional-grade charcoal, so be sure to review the Lighting Instructions to see if you have what it takes!.
