A wok is a utensil used in the preparation of certain foods, where the food is usually stir fried in it, although it allows for a great variety in types of food preparation.
Seven of Nine owned and frequently used a wok to prepare food in.
In 2374 Sevens wok caught on fire while preparing a dish for her wife, captain Kathryn Janeway. The fire was caused because the couple was engaged in personal interaction, leaving the wok unattended for several minutes. Janeway was a bit dismayed at how quickly Seven managed to douse the flames by shutting of the heating unit and placing the lid on the wok. It left a distinct impression that it was far from the first time that Seven had put out a blazing wok. (JB: "Just Between a Rock & a Hard Place")
