The basic kushikatsu in Kanto eastern Japan area including Tokyo is made with diced pork rib in 3–4 cm (1.5 in) cubes, skewered with sliced onions or leeks. Battered with fresh egg, flour and thin layer of panko crust, the skewer is deep fried in vegetable oil — cottonseed, soybean, canola or rapeseed oil. At the table, skewers are seasoned with thick brown sauce, sweeter than Worcestershire sauce, with mustard if they have it in the cruet stand.
