蒸

This kanji is used in compounds for the steaming of food and also for smoking/fumigation. Here we have the Japanese once again trying to replicate the French cuisine, only with a twist, steaming food with flowers (think of flower-smoked ham for example). Flowers must first be completely soaked in water, and then poured over a thin piece of flooring under which there is an oven fire.
