Gac Fruit, or simply Gac as it is referred to in Southeast Asia, is a tropical vine that is botanically classified as Momordica cochinchinensis. It is also commonly known as Baby Jackfruit, Spiny Bitter Gourd, Sweet Gourd or Cochinchin Gourd. It has an extremely short season, a mere two months long, but the fruit plays an important role in celebratory dishes as well as in natural medicine. Until recently, Gac has been a mystery outside of its native lands, but the juice has since been marketed as a dietary supplement because of its allegedly high phytonutrient content.
