Upo
Upo is called a bottle gourd in English because of its elongated shape.
The plant has the scientific name Lagenaria siceraria. Its fruit is a very popular vegetable in the Philippines.
You can simply sauté it with ground beef to make ginisang upo, which literally means “sautéed bottlegourd.”
The upo gourds in the featured looks to have white mottled skin. Usually the variety grown in the Philippines is a smooth green?
