1 can frozen orange juice
2 to *2 ½ cups milk
2 ½ cups ice
1 ½ teaspoon vanilla
4 tablespoons agave
Place milk, vanilla, and agave in blender.
Then add frozen orange juice and ice in blender, blend until smooth.
If it's still too thick add 1/2 a cup more milk. (This can happen because the thickness of frozen orange juice is different from brand to brand.)
This makes about 4 large drinks.
