Sure you can do this without the food coloring...but it wouldn't be a Shamrock Shake...would it?
The recipe from Epicurious said to use 1 teaspoon of peppermint extract but everyone complained about it being too overpowering. So I opted to use mint extract (which is a combination of spearmint and peppermint oils) and less of it.
- 1-1/2 cups vanilla ice cream (so much easier if you weight it)
- 1/2 cup milk
- 10 drops green food coloring
- 1/2 teaspoon mint extract
- whipped cream (optional)
- maraschino cherries (optional)
Put all ingredients in a blender and blend until smooth.
Pour in a glass and, if desired, top with whipped cream and a cherry.
