Building the eternal pizza:
Researchers at a U.S. military lab in Massachusetts are closing in on a recipe that doesn't require any refrigeration or freezing.An army travels on its pepperoni...
"You can basically take the pizza, leave it on the counter, packaged, for three years and it'd still be edible," said Michelle Richardson, a food scientist at the U.S. Army Natick Soldier Research, Development and Engineering Center.
Scientists at the Natick labs also are responsible for developing equipment and clothing that improves soldiers' combat effectiveness and their survival, but the quest for good pizza has become known as the holy grail there.
Pizza is one of the most requested items when soldiers are asked every year what they'd like to see in their rations, said Richardson, who has spent nearly two years developing the recipe in a large kitchen full of commercial equipment.
