Goya: Okinawa's Bitter Melon

The green, ridged, unapologetically bitter vegetable at the heart of Okinawan home cooking, and how to make goya chanpuru.
The short answer

Goya is the Okinawan name for bitter melon, a green, bumpy vine fruit eaten as a vegetable. It's the signature ingredient of Okinawan home cooking, best known in goya chanpuru, a stir-fry with tofu and egg. It's eaten unripe, while it's still green and bitter, and the bitterness is the point.

Few vegetables divide a dinner table like goya. Children in Okinawa famously push it to the side of the plate. Adults eat it without comment. Somewhere in between, most people who grow up with it come around.

A note from the founder

The founder of Javier Discovers spent three years of his childhood in Okinawa, the first in a Japanese neighborhood off base. Goya was on the table at nearly every meal. A neighbor grew it on a trellis beside her house and called it her medicine. To a kid, it was the bitterest thing he'd ever tasted.

Four Things to Know About Goya

One plant, many names

Goya is Momordica charantia, called bitter melon or bitter gourd in English, karela in India, and ampalaya in the Philippines.

Eaten green

It's picked unripe, while it's firm and bitter. Left to ripen, it turns yellow-orange and splits open to reveal bright red seeds.

A summer staple

Goya loves heat. In Okinawan summers it climbs trellises in backyards, and many homes grow it as a leafy "green curtain" to shade their windows.

A good everyday vegetable

Like most green vegetables, goya is low in calories and a good source of vitamin C and fiber. In Okinawa it's simply part of ordinary meals.

How to Make Goya Chanpuru

"Chanpuru" is an Okinawan word for something mixed together, and goya chanpuru is the island's best-known home dish: a quick stir-fry of goya, firm tofu, egg, and usually pork. In Okinawa, sliced pork or canned luncheon meat are both common. It takes about twenty minutes.

Serves 2 to 3

Ingredients

  • 1 goya (bitter melon)
  • 1 block firm tofu (about 14 oz), drained and pressed
  • 4 oz thinly sliced pork belly or luncheon meat
  • 2 eggs, beaten
  • 1 tablespoon neutral oil
  • 1 tablespoon soy sauce, plus a pinch of salt
  • Optional: a pinch of dashi powder, and bonito flakes to finish

Steps

  1. Cut the goya in half lengthwise and scoop out the seeds and white pith with a spoon. Slice thinly into half-moons.
  2. Toss the slices with a pinch of salt and let them sit 10 minutes. Rinse and squeeze gently. This softens the bitterness without removing it.
  3. Heat the oil in a large pan. Tear the tofu into rough pieces and fry until golden on a few sides. Set aside.
  4. Add the pork and cook until browned, then add the goya and stir-fry 2 to 3 minutes until bright green and just tender.
  5. Return the tofu, season with soy sauce and dashi, then pour in the egg and fold gently until just set.
  6. Serve hot with rice, topped with bonito flakes if you like.

Look for goya at Asian and Indian grocery stores, often labeled bitter melon or karela. Choose firm, bright green ones.

Beyond chanpuru

Other Ways Okinawans Eat Goya

Goya also shows up as a crunchy salad with tuna or mayonnaise, as tempura, pickled, and as goya tea made from dried slices. Okinawan shops sell goya chips and other snacks, and you'll find it on menus all over the islands in summer.

Goya is often mentioned alongside Okinawa's status as one of the world's Blue Zones, regions researchers study for their unusually high numbers of very long-lived people. Researchers point to the traditional diet as a whole, along with daily movement and close community, rather than to any single vegetable.

  • Pregnant or trying to conceive? Bitter melon in medicinal amounts isn't recommended during pregnancy. Ask your doctor before eating it regularly.
  • Skip the seeds. Remove the seeds and pith before cooking. The seeds of ripe bitter melon are not recommended, especially for people with G6PD deficiency.
  • Start small. Large amounts can upset the stomach.
