1. Purchase a 4 oz bottle of Angostura bitters.
2. Pat yourself on the back, because it’s cool to make your own stuff.
3. Deposit five whole cloves into the bottle.
4. Allow to steep for 48 hours, shaking the bottle several times a day.
5. Pour into another container, then strain the bitters back into the bottle using a small funnel and a fine-mesh strainer, such as a tea strainer.
