Heat the butter in a 4-quart saucepan over high heat; when about half melted, add the remaining ingredients. Stir, cover and cook over high heat until mixture comes to a strong boil, about 10 minutes. Stir, then reduce heat and simmer covered for 20 minutes. Remove cover and continue cooking until sweet potatoes are very tender, about 20 minutes, stirring occasionally. Remove from heat and discard cinnamon sticks. Serve immediately, undrained.
