Eureka!'s most flexible compact cook system, the Gonzo Grill System functions as either a grill, griddle or a stove—all in a single compact package. Eureka!'s engineered simmer control valve, powered by Jetboil, generates a precise, consistent cooking flame with each turn of the dial. Eureka!'s reversible cast-iron cook surface switches from a griddle top to a grill surface; remove the cast iron and the recessed stove grate allows for boiling water and sautéing vegetables.
