Mushy peas Mushy peas Mushy peas are dried marrowfat peas which are first soaked overnight in water with sodium bicarbonate (baking soda), then rinsed in fresh water and simmered with a little sugar and salt until they form a thick green lumpy mash. Sometimes mint is used as a flavouring. In Northern England and the Midlands they are a traditional accompaniment to fish and chips, although their appeal has spread. All over Britain, but particularly in Northern England, they are commonly served as part of the popular snack of pie and peas (akin to the South Australian pie floater, but with mushy
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
