What food did Shackleton take on his trans Antarctic expodition?

Ernest Shackleton's Imperial Trans-Antarctic Expedition (1914-1917) took a variety of food supplies, including pemmican (a high-energy mixture of fat and protein), biscuits, chocolate, and canned goods like meat and vegetables. The crew also packed supplemental items such as sugar, tea, and dried fruits. These provisions were chosen for their long shelf life and nutritional value, crucial for the expedition's survival in harsh conditions. However, many supplies were later compromised due to the conditions faced after their ship, the Endurance, was trapped in ice.
