Gulai is a class of spicy and rich stew commonly found in the Malay Archipelago. The main ingredients of the dish are usually poultry, goat meat, beef, mutton, various kinds of offal, fish, and seafood, as well as vegetables such as cassava leaves, unripe jackfruit, and banana stem.

The jackfruit is the fruit of jack tree Artocarpus heterophyllus, a species of tree in the fig, mulberry, and breadfruit family (Moraceae). The jackfruit is the largest tree fruit, reaching as much as 55 kg in weight, 90 cm in length, and 50 cm in diameter. A mature jackfruit tree produces some 200 fruits per year, with older trees bearing up to 500 fruits in a year. The jackfruit is a multiple fruit composed of hundreds to thousands of individual flowers, and the fleshy petals of the unripe fruit are eaten.
