Because we had it on our trip to Florida... And I was awesome
Key lime milkshake:
I carton (1.75 pint of vanilla ice cream)
1/2 cup of freshly squeeze key lime juice
In a blender (mine came with a milkshake attatchment so additional liquid was not necessary) mix the 2 ingredients until completely blended... Enjoy it right away for a different yet delicious milkshake.
