Kantola
Momordica balsamina
Kantola (Momordica balsamina), also called balsam apple or balsam pear, is a small, warty, spindle-shaped gourd native to Africa and Asia that carries a complex bitter-sweet flavor prized in traditional cuisines across both continents. Unlike its intensely bitter cousin bitter melon, kantola offers a milder, more approachable bitterness balanced by a pleasant sweetness when cooked. The bright orange fruits that split open at maturity to reveal crimson-coated seeds are as ornamental as they are culinary, making this a plant that bridges the vegetable garden and the flower border.
• Known as "balsam apple" for the bright orange, apple-shaped ripe fruits
• The species name "balsamina" refers to the balsam-like resin the plant produces
• Less bitter than common bitter melon (Momordica charantia), making it more versatile in cooking
• Both the young green fruits and tender shoots are eaten as vegetables
• Naturalized pantropically and often treated as a weed despite its edibility

Fun Fact
When kantola fruits ripen fully, they put on one of nature's most dramatic shows: the orange fruit suddenly bursts open at the tip, revealing seeds coated in a brilliant crimson, sticky aril that contrasts vividly with the deep orange rind. This startling display evolved to attract birds, but it also makes the plant a striking ornamental — if you can resist eating the green fruits long enough to let them ripen.
