Some foods that start with "w" are walnuts, wakame, watercress, watermelon, wheat, wheat germ, whelks, whiting, whitefish, wild rice and Westphalian ham. Other foods are Weisswurst, Wensleydale cheese and wax gourd.
Wakame is a type of seaweed that's used in Japanese and Korean cuisine. It's abundant in minerals, especially iodine. Whelks are sea snails with whorled shells. They're also part of Asian cuisine.
Whiting and whitefish aren't interchangeable. Whiting is also called silver hake and has a flaky, white flesh. Whitefish can refer to any type of fish with white flesh. A specific type of whitefish belongs to the Coregoninae subfamily. These types of fish are found in freshwater and are related to salmon.
Wild rice isn't really rice. It is rather a grain from an aquatic plant native to North America. The wild rice that's grown in Minnesota is harvested in the traditional way, with two people in a canoe. One person operates the canoe while the other one collects the rice.
Weisswurst is a type of sausage that's very much like bratwurst. It's a pale sausage with a delicate taste and is good for frying. Westphalian ham is traditionally smoked over ash or beech chips with a bit of juniper. It's also cured with juniper berries.
