Talong is a Filipino word for Eggplant. Talong is one of the kinds/varieties of vegetables (Gulay) in the Philippines. There are several kinds available in the Country which Ive already seen, not only the violet ones, but rarely found in the wet markets, the green and rounded and the long and green.
In an African shop in Germany, I saw a yellow variety, but what is always available, specially in Turkish and Moroccan Food Shops and in most local groceries/ shops are the big and oval or oblong.
