Use the paragraph to answer the prompt.
Native Americans dried strips of meat, pounded it into a paste, and then mixed it with fat. Sometimes they added berries and sugar. Then they pressed it into small cakes. They called these cakes pemmican. Pemmican didn't spoil, and it provided lots of energy for people traveling or going hunting. Today explorers still carry and eat this food.
