Put the pineapple pieces into a 32-ounce Mason Jar

Pour in the orange vodka, and seal it with a lid.

Set aside for 48 hours. Shake the jar every now and then.

Strain out the vodka into another 32-ounce Mason Jar. Reserve the pineapple.

In a cocktail shaker filled fill ice, shake 5 oz. of the pineapple-infused orange vodka for 30 seconds.

Strain into a chilled martini glass garnished with pineapple. Cheers!
