- Slice the pineapple into chunks and place into a large container, preferably one with a spigot, such as an ice tea jug.
- You may not need all the pineapple, just enough to fill the jug.
- Pour the vodka over the pineapple using more if needed to cover pineapple.
- Cover, and allow to sit for 3 to 4 days, or longer, to infuse the Vodka with the pineapple juice.
- To serve, pour into a shaker filled with crushed ice.
- Shake well to chill and pour into martini glasses.
