Put vodka, dill, lemon and orange zest in a sealable glass jar. Seal and shake, then let steep at room temperature for one day, or 24-36 hours. Remove the citrus zests and dill and add the spices to the liquid.
Let steep for another 3-7 days, taste every day after the 3rd day and if a stronger flavor is desired, then continue to steep for another week or so. When the aquavit has the taste you want, strain it through a cheesecloth and store in a clean glass bottle at room temp or in the fridge.
Notes
*You can also use wheat-based vodka or other vodka you have on hand.
