Energy efficient cookware is provided that includes a base (204) and a wall (206), a radial pattern of flame guide channels a radial pattern of perturbation channels (216) are connected to the base bottom. The guide channel (208) accepts a flame and guides it to the perimeter from the central region. The perturbation fin (218) generates turbulence in the guided flame to increase heat transfer from the flame to the base and the fins. An insertion plate (700) is disposed on the base top side. The plate has a pattern of boiling nucleation stubs (704) with a venting feature on one side. The stubs (704) interlay liquid input ports (706) and vapor exit ports (708). A volume of the liquid is between the stub and base top. The liquid rapidly vaporizes when the base is heated. The vapor migrates from the stub top surface and through the exit port, where the volume is refilled with liquid from the input port.
