Jackfruit is the world's largest fruit. It produces giant bumpy fruits that have a bunch of super sweet yellow pouches inside when ripe. Jackfruit is one of my all-time favorite fruits. However ripe jackfruit is not the jackfruit that is used as a meat replacement. Young Jackfruit is the version of jackfruit that is used as a meat replacement. It is essentially just under-ripe jackfruit. Young jackfruit has the texture of meat and it has a pretty neutral taste, which makes it a great replacement for shredded chicken.
