Cottage Loaf and Tin Bread contrasted
Mrs.Beeton, 1863
The cottage loaf gives a much larger area of crust than other shapes, and so, according to Mrs.B is unsuitable for toast, "not being a good shape, and too crusty for the purpose."
It is said to have been the commonest bread form until the second world war (Mason+Brown 2004).
Cottage loaves are unusually tricky to make, and now rare.
The name is known with certainty at least from the early 19th Century, the OED finds an early reference in the letters of the landscape painter and draughtsman, John Constable (1776–1837) " I send you a cottage loaf for Sunday." The origin of the form is unclear, but there is a similar pain chapeau (hat bread) in Brittany.
