On a recent U.S. National Forest expedition, we broke a golden rule of camping and snapped off a piece of nature to take with us. It was to make an emerald beverage ... a pine sap-arac. Infused into a tart lemon-lime juice that's more whiskey sour mix than lemonade, this uses the bitter medicinal notes of pine to make whiskey that much sweeter. The stuff's fine hand-mixed and room temp if you're still out in the pines. But if you bring the loot back home, blended is better.
