Grapefruit orange bitters

 Zest of 2 grapefruits

1/4 cup chopped dried grapefruit peel or orange peel

1/2 tsp gentian root

1 tsp coriander seeds

6 green cardamom pods, cracked

1 tsp dried hops

1 cup Spirytus 192-proof alcohol, or 2 cups 100-proof vodka

2 tbsp honey? Maybe simple syrup instead?

Combine everything except the honey. Store for 2 weeks, shaking daily. Strain out the solids, put the solids in a pot with water (3c minus the amount of alcohol used) and simmer 10 min. Store the water infusion for 1 week, shaking daily. Add everything together, add honey, store 3 more days.

(The books says add honey, but when I do, it doesn't really mix in. Maybe I should add it to the water infusion while it's hot, or maybe just use sugar/syrup.)
