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 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
