The Old Abbott's Bitters

Crush cardamom, allspice, and star anise. Add all ingredients to 4 1/2 cups of rye, like Rittenhouse. Seal in a Mason jar for ten days, shaking daily. Then pour through a cheesecloth to remove large solids and strain three times using a paper coffee filter, changing when clogged. Add 1 1/4 cups of water and reseal. Filter again after two days. Age the infusion for six months in a Mason jar with charred oak chips.
