chazzerking makes pineapple-vanilla vodka: Cut one large or two small pineapples into chunks and place the chunks in a clean, one-gallon glass jar. Add one split vanilla bean and two 750-milliliter bottles of vodka. Cover the jar tightly and place it in a cool spot. Shake the jar gently each day for 10 days, then strain out the pineapple. Decant the vodka into bottles, leaving the vanilla bean in the infusion.
