The Teasle Gourd (Momordica subangulata), known as bhat karela or spiny bitter gourd, is a lesser-known but highly prized climbing gourd from the foothills of the eastern Himalayas. Its small, oval, softly spined fruits are considered a delicacy in Assamese, Bengali, and Nepali cuisine, where their mild bitterness and firm texture make them ideal for stir-fries and stuffed preparations. Like its famous cousin bitter melon, the teasle gourd is valued both as a vegetable and in traditional medicine, though it remains much less known outside its native range.

The teasle gourd is part of a trio of Momordica species that form the backbone of bitter-flavored cooking across northeastern India: the common bitter melon, the spiny gourd, and this, the teasle gourd. Local cooks insist that the three have distinct flavors and should never be substituted for one another — a level of culinary specificity that speaks to the deep food culture of the eastern Himalayas.
