What is Jackfruit? Native to Southeast Asia, Jackfruit is the largest tree-borne fruit in the world and is capable of reaching up to 100 pounds! With a spiky exterior and fibrous interior, the fruit’s varying stages of maturity yield both different textures and flavors. Bar-B-Que Jackfruit makes a great sandwich topped with coleslaw, and also goes great on a salad, in a wrap, or over rice.
