Green St. Patrick's Day Cocktail, shamrock sour.

Shamrock Sour St. Patrick’s Day Drink

I decided to put an Irish twist on one of my favorite cocktails, the whiskey sour. Combine that idea with your favorite Irish whiskey and now we’re talking!

Of course, I gave it a bit more focus on lime for the green garnish and a little droplet of green food coloring because your cocktail must be green on St. Patrick’s Day!

If you prefer amaretto sours, you can certainly apply the recipe below for amaretto liquor as well.

Shamrock Sour Ingredients

  • Lime Juice
  • Irish Whiskey (or your favorite whiskey of choice)
  • Lemon Juice
  • Green Food Coloring (a tiny drop)
  • Simple Syrup
  • Lime Wedge for Garnish
Shamrock Drink Stirrers

I decided to give mine even more of the St. Patrick’s Day touch by making easy DIY shamrock stirrers. These can hardly be called a DIY, however, because they’re that easy.

Visit your craft store and grab some craft shamrocks (felt, paper or anything you can find will work) and bamboo skewers.

  • Glue the shamrocks onto the skewers and ta-da: St. Patrick’s Day drink stirrers!
  • If you have extra, shorten them and use for appetizers or cupcake toppers.

Recipe Notes & Details

  • You can use any whiskey variety you like, I just suggested Irish whiskey given the Irish holiday!

  • You can make this green cocktail in advance and refrigerate until ready to serve!

  1. Really — a 1/2 cup of simple syrup for the Shamrock Sour?? That seems quite sweet!!

      1. David McDermitt says:

        1/4 CUP?
        Shouldn’t that be 1/4 Tablespoon or 1/4 oz?
