Ingredients

3 lemons 

3 tangerines 

1 1/4 cups kumquats, halved 

1 bottle (750 milliliters) vodka, such as Smirnoff 

1 1/2 to 2 1/2 cups  Simple Syrup 

Preparation

Peel strips of zest from lemons and tangerines with a vegetable peeler, avoiding white pith; reserve fruit for another use. Put zest, kumquats, and vodka in a large nonreactive jar; cover and let stand at room temperature 2 to 3 days. Stir in simple syrup to taste. Refrigerate 1 day.

Strain through a fine-mesh sieve, reserving some fruit for garnish, if desired. Divide among clean jars. Add some soaked fruit or strips of zest, if desired. Refrigerate up to 3 months.
