Water biscuit

A water biscuit (Commonwealth English) or water cracker (American English) is a type of savoury cracker. It is named for its simple recipe, consisting of just water and flour. They are thin, hard and brittle, and usually served with cheese or wine. Originally produced in the 19th century as a version of the ship's biscuit, water biscuits continue to be popular in Australia, New Zealand, South Africa, Ireland, and the United Kingdom, with the leading brands (Carr's and Jacob's) selling over seventy million packets a year. Water biscuits are also popular in Chile. In 1801, Josiah Bent began a baking operation in Milton, Massachusetts, selling "water crackers" or biscuits made of flour and water that would not deteriorate during long sea voyages from the port of Boston. His company later sold the original hardtack crackers used by troops during the American Civil War.
