Controlled evaporation: New technologies require innovation. For state-of-the-art stoves with cooktop extractor fans, Smart Steam is the best match. Strategically placed lid openings and a clever indent in the rim of the pot ensure that the steam comes out on the side and goes directly into the extractor fan. Evaporation can be managed by slightly turning the lid. The grey silicone ring ensures a great fit so that unpleasant food odors are kept at bay.
