Start out by getting everything needed for making the drink gathered up.
Grab your rocks glass and shaker. Fill both almost to the top with ice.
Grab up your peach schnapps and jigger. Use the jigger and measure 2 oz of peach schnapps. Pour that into the shaker.
Grab up your orange juice and jigger. Use the jigger and measure 4 oz of orange juice. Pour that into the shaker.
Grab up the shaker top and secure it on the shaker.
Shake it well until the outside of the shaker is cold to the touch. This typically takes about 15 or so seconds.
Grab up the Hawthorne strainer. Remove the shaker top and replace it with the strainer.
Pour the drink from the cocktail shaker into the rocks glass.
