Mushy peas Without the colourant the dish would be murky grey. In July 2010 an EU directive required the warning label "May have effects on activity and attention in children" to be applied to foods containing tartrazine. 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
Freezing-point depression in the melting-point depression observed when the melting point of an impure solid mixture is measured with a melting-point apparatus, since melting and freezing points both refer to the liquid–solid phase transition (albeit in different directions). In principle, the boiling-point elevation and the freezing-point depression could be used interchangeably for this purpose. However, the cryoscopic constant is larger than the ebullioscopic constant, and the freezing point is often easier to measure with precision, which means measurements using the freezing-point depression are more precise. Also this phenomenon is applicable in preparing a freezing mixture for use in an ice-cream machine. For
