1/2 oz Creme De Menthe (Green)
1/2 oz Banana Schnapps
1/2 oz Grenadine.

Teaspoons, Jigger, Shot Glass.

Pour the Grenadine into a 2 oz. Shot Glass. Next, slowly, slowly, pour the Banana Schnapps over the back of a spoon down the side of the glass.
The slower you pour, the better the layering effect you'll get. Repeat the slow pour technique with the Creme De Menthe. It takes a little practice, but the end result is worth the effort. Cheers!
