This one comes from Betty Crocker.com and is a slightly different version than the 'other' recipe found on this site.
- Fill martini shaker (or other container with a lid) with ice.
- Pour pineapple juice and vodka into the shaker. Add grenadine.
- Gently shake, and pour into martini glasses.
- Garnish with cherry. It looks pretty at the bottom of the glass.
