1/2 shot 100 proof Vodka 1/4 shot Sweet and sour 1 splash concentrated Orange juice 1 splash Club soda 1 dash Rose's Grenadine
Start with the vodka, 100 proof is important, then sweet and sour, etc. right in order. It naturally sets up a base for the grenadine to float through. The grenadine dash should top off the shot glass and filter down, leaving no grenadine on top. Tapping the shot while steadying the top of the glass helps this.
