Jaew bong

Jeow bong (Lao: ແຈ່ວບອງ, Thai: แจ่วบอง; rtgs: Chaeo Bong) is a sweet and spicy Lao chili paste made with Lao chilies, galangal and other ingredients commonly found in Laos. Its distinguishing ingredient, however, is water buffalo skin.

It is eaten usually by dipping Lao sticky rice or a raw/parboiled vegetable in it. It's also a condiment for a Lao riverweed snack called Kaipen. Jeow bong lasts for a long time, does not spoil easily and can be either on the spicier or sweeter side, depending who makes it. Characteristically, it is both sweet and spicy.
