Contrary to what the name might suggest, marrow fat is not a type of squash or a fatty substance from an animal, but a large, mature, dried pea. The marrowfat pea is a specific cultivar of the common garden pea (Pisum sativum) harvested much later in its growing cycle.

Quick Summary

An exploration of marrowfat peas, a specific type of dried pea often confused with marrow squash. The article covers their unique characteristics, how they differ from standard garden peas, their key culinary applications, nutritional profile, and proper preparation methods.

Key Points

Marrowfat is a pea, not a squash: The term 'marrow fat' refers to a specific type of dried pea, not a marrow (squash).
Dried and matured: Unlike garden peas, marrowfat peas are left to mature and dry naturally in the field before harvesting.
Ideal for mushy peas: Their large size, starchiness, and thin skin make them perfect for cooking into the creamy consistency of traditional British mushy peas.
High in nutrients: They are a good source of protein, dietary fiber, iron, and other essential minerals, and are low in fat.
Versatile culinary uses: Besides mushy peas, they can be used for wasabi peas, roasted snacks, and as a thickening agent for soups.

Marrowfat Peas: The True Identity of 'Marrow Fat'

Many are confused by the term "marrow fat," often mistaking it for marrow squash or animal fat. However, it specifically refers to the marrowfat pea, a pulse prominent in British cuisine. Unlike young garden peas, marrowfat peas mature and dry on the vine. This process makes them larger, starchier, and thicker-skinned.

How Marrowfat Peas are Processed

Preparing dried marrowfat peas for dishes like mushy peas involves soaking them for 12-16 hours, often with baking soda, to soften their skins. They are then simmered until they form a thick, pulpy texture. Seasoning with salt and sometimes mint or butter finishes the dish, commonly served with fish and chips. Canned versions offer a convenient alternative.
