I brought back a big bag of incredible limes from SHOT and had a little epiphany... the peels got chopped and dried, then flooded with tequila. The lime infused tequila became the base for bitters designed to add a little something to margaritas. I added gentian, Cascade hops, lemon, grapefruit, and clementine peels. Then I added spices that speak to me of Mexico: cardamom, coriander, star anise, licorice root, vanilla, and cinnamon. The urge to add hot peppers was beaten back, but black pepper, juniper berries, and cloves went in.
Started with Kirkland ready-mixed margarita mix and added their blanco tequila and a little triple sec before adding the bitters at the end on top of the lime wedge garnish. Have to say it was mighty good!
