Visual representation of my heart
A: Beef jerky is strips of marinated, dried meat that can be kept without refrigeration. Generally jerky is made with a lean cut of beef, such as sirloin, top round or round eye, as fat left on the final product will cause it to spoil more quickly. The meat is cut into strips approximately 1/2" thick against the grain. The strips of beef are then marinated for approximately 24 hours in a simple mixture of soy sauce, Worcestershire sauce, onion salt, garlic powder and pepper (although many variations exist). The meat is then dehydrated either in a dehydrator or in a low temperature oven - if using the oven method, it is advised that the oven door be left slightly ajar for the moisture to evaporate. Interestingly, beef jerky is selected by astronauts on space flights because it is light weight and high in nutrition. I wonder if I can interest them in taking my heart on a space mission with them...
