Get a stir-fry moving in seconds with this Smeg induction hob. Built-in and 75cm wide, its acid-etched glass top drops straight into an existing gas hob cut-out, so there's no reworking the worktop. The four zones each measure 180mm across, and heat only forms where the pan actually sits, which means no power goes into warming bare glass. Nice touch. Made in Italy, the surface holds its shape at temperatures up to 700°C, so heavy pans and hard use won't warp it.
