'earth cookie', pronounced [bɔ̃bɔ̃ tɛ]) is a famine food that is eaten in Haiti by children or expectant mothers.

[3] Due to their mineral content, mud cookies were traditionally used as a dietary supplement for pregnant women and children.

[2][5] Many Haitians believe they contain calcium which could be used as an antacid and for nutrition, but this is disputed by doctors who warn of tooth decay, constipation, and other complications.[which?

][1][5] The production cost is cheap; the dirt to make one hundred cookies was five US dollars in 2008 (about 5 cents apiece), even after increasing by $1.50 since 2007.

[3][6][needs update] The taste has been described as having a smooth consistency that immediately dries the mouth, with a pungent aftertaste of dirt that lingers for hours.
