1 c. sugar
4 c. water
red food coloring or beet juice

Boil water and sugar until sugar dissolves. Cool. Add enough food coloring to make liquid medium pink.

Cooks Note: Some questions exist as to whether red food coloring may be safe for hummingbirds. If you have beet juice (saved from canned beets) available, add a few tablespoons to the water to color it naturally. Otherwise, you can also choose to omit the coloring altogether.
