Marrowfat peas Marrowfat peas Marrowfat peas are green mature peas that have been allowed to dry out naturally in the field, rather than be harvested whilst still young like the normal garden pea. They are used to make mushy peas, and also the snack food wasabi peas. Marrowfat peas with a good green color are exported from England to the Middle East and 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. Marrowfat is a traditional, starchy, large-seeded variety of pea ("Pisum sativum" var.
Flash freezing than the poly-crystalline solid that flash freezing results in. Flash freezing is used in the food industry to quickly freeze perishable food items (see frozen food). In this case, food items are subjected to temperatures well below water's melting/freezing point. Thus, smaller ice crystals are formed, causing less damage to cell membranes. Flash freezing techniques are used to freeze biological samples quickly so that large ice crystals cannot form and damage the sample. This rapid freezing is done by submerging the sample in liquid nitrogen or a mixture of dry ice and ethanol. American inventor Clarence Birdseye developed the "quick-freezing"
