In a blender or big bowl, blend the milk, sugar, vanilla extract, and the food coloring for about 1 minute. Or until all the sugar dissolves.
Pour your limber mix equally into disposable cups with lids. Then freeze the limbers for at least 12 hours. ¡Buen provecho!
Notes
Freezing- A Limber can take 8-12 hours to set. But a creamy limber, like this one that is made with milk, might take a little longer. I always leave them overnight to make sure they set.
