Caught in the nipa swamps of Bulacan are small fat crabs called damuko. They are salted and cooked in tuba (nipa wine) in a clay pot. Just before serving, the inside of the palayok is flamed in order to remove the sour taste of the liquor. The damuko has a sweetish flavor, with a hint of alcohol, and even the plump tiny claws can be cracked and eaten.
Ang damuko ay kamag-anak ng alimango, alimasag at talangka. Mas malaki ito sa talangka at maliit sa alimasag. Makapal at mas magaspang ang talukap nito sa talangka. Mamerde-merde ang taba o aligi, at medyo mapait-pait daw ang lasa.
