Marrowfat peas are green mature peas (Pisum sativum L. or Pisum sativum var. medullare) that have been allowed to dry out naturally in the field, rather than being harvested while still young like the normal garden pea. They are starchy, and are used to make mushy peas. Marrowfat peas with a good green colour are exported from the UK to Japan for the snack food market, while paler peas are used for canning. Those with thin skins and a soft texture are ideal for making mushy peas.
Its name 'marrowfat' was coined around 1730 from marrow and fat. Another source says the peas were named because people wanted plump (fat) peas of the Maro variety, a Japanese variety introduced to the UK 100 years ago; this is unlikely, as the first English usage of "marrowfat" to refer to peas predates the introduction of the Maro pea by almost two centuries.
