Somehow St. Patrick's Day has lost it's way.
 It's not really about the Saint or even celebrating Irish-American's ethnicity.  Usually I think Hallmark is to blame, but in the case of St. Patty's I'm betting on liquor distributors taking advantage of a vulgar stereo-type...and it's worked.  St. Patricks Day is predominantly thought of as a day to drink.  

I'm pretty sure the Irish Cream and Irish Whiskey folks were in on the corruption of this holiday...the Midori folks just got lucky their liqueur was green and fit the bill, and that's why the most popular shot on St. Patrick's Day is the Shamrock Shooter.

                      Cheers! XO  Martha

Shamrock Shooter
2 oz. Midori Melon Liqueur
1/2 oz. Irish Whiskey (like Jameson's)
1/2 oz. Irish Cream Liqueur (like Bailey's)

Pour all the liquors into a shaker filled with ice.  Shake vigorously, then strain into a shot glass.  

(I personally think there could be less Irish Cream and more Irish Whiskey in this drink!)

By the way, I love these little shamrock shot glasses I found at the consignment shop.  They remind me of the Irish Coffee glasses my parents had, back in the day!
