Ingredients

4 organic oranges, well scrubbed 

2 organic Meyer lemons, well scrubbed 

1 tablespoon gentian root chips 

1 teaspoon fennel seeds 

1/2 teaspoon coriander seeds 

1/2 teaspoon whole cloves 

1 cinnamon stick 

1 750-ml bottle good-quality vodka, such as Prairie Organic 

Preparation

Heat oven to 200 degrees. Using a vegetable peeler, peel citrus to make strips of zest, being careful not to remove pith. Arrange in a single layer on a parchment-lined baking sheet and bake until dry, about 1 hour. Let cool.

Transfer zest to a 1-quart glass jar and top with remaining ingredients. Cover tightly and store in a cool, dark place for three weeks, shaking jar once a day.

Pour liquid through a fine mesh strainer or paper coffee filter and into a clean jar. Add citrus zest and discard aromatics.
