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 have reportedly been revived after surviving for thousands of years frozen in ice. Many plants undergo a process called hardening, which allows them to survive temperatures below 0 °C for weeks to months. The nematode "Haemonchus contortus" can survive 44 weeks frozen at liquid nitrogen temperatures. Other nematodes that survive at temperatures below 0 °C include "Trichostrongylus colubriformis" and "Panagrolaimus davidi". Many species of reptiles and amphibians survive freezing. See cryobiology for a full discussion. Human gametes and 2-, 4- and 8-cell embryos can survive freezing and are viable for up to 10 years, a process known as cryopreservation. Experimental
