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.
Freezing-point depression a result of freezing-point depression, radiators do not freeze in winter (unless it is extremely cold, e.g. ). Road salting takes advantage of this effect to lower the freezing point of the ice it is placed on. Lowering the freezing point allows the street ice to melt at lower temperatures, preventing the accumulation of dangerous, slippery ice. Commonly used sodium chloride can depress the freezing point of water to about . If the road surface temperature is lower, NaCl becomes ineffective and other salts are used, such as calcium chloride, magnesium chloride or a mixture of many. These salts are
