St. Patrick's Day Cocktail - The Shamrock Sour, a green drink.

Yes, green beer might be the norm for this Irish celebration, but my Shamrock Sour is so good that I’m sure it will quickly become your favorite St. Paddy’s day beverage.

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

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

  • 2 tablespoons lime juice
  • ½ tablespoon lemon juice
  • ¼ cup simple syrup
  • 2 ounces Irish whiskey (you can choose your favorite whiskey)
  • 1 tiny drop of green food coloring
  • lime wedges for garnish

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.
