This recipe is really just a 3-2-1 ratio with almost endless adaptations. Start with a base liquor of your choice. Add something sour -- citrus or another unsweetened, tart juice. You can even add a splash of brine from pickled vegetables or a little vinegar to take the cocktail in the direction of a shrub, which has popped up on drink menus all over because it's so refreshing. Finally, add something sweet -- basic simple syrup or just about any other liquid sweetener you have on hand. Once you are ready to shake it with ice, you can personalize it further by throwing a few herb sprigs or pieces of fruit in the shaker.
Finish with a topper of seltzer, prosecco or another fizzy beverage, if you like. The proverbial cherry on top can be any garnish you have on hand -- fruit, pickles, candy, herbs, you name it.
Begin with simple combinations -- see our suggestions below -- and then experiment to find the ones you like the most.
