How Many Shamrock Shakes Do You Have To Drink Before You Pee Green?
This is almost as philosophical a question as "how many licks does it take to get in the center of a tootsi-roll pop?"
Unfortunately, I don't know the answer to either question, but I do know that if for some reason you're super motivated to make McDonald's Shamrock Shake, instead of buying it, here's the recipe:
McDonald's Shamrock Shake Copycat Recipe
(makes 1 giant shake, or 2 generously sized shakes)
3 cups good quality vanilla ice cream
1 3/4 cups 1% milk
1/2 teaspoon peppermint extract
Green food coloring, if desired
But is anyone actually that motivated?
