One of my favorite Summer cocktails is the bramble, a mix of gin, lemon, fresh blackberries, and blackberry liqueur. It's also a recipe that's easy to play around with, which makes for a fun day of improvising — something I did this past weekend. Instead of gin, I chose tequila as the base spirit; to me, tequila is the perfect complement to warm weather and fresh fruit.
For anyone craving a fruity cocktail minus the calories, this variation of a classic bramble is a good choice. Like most brambles, it avoids store-bought mixers or fruit juice, but relies on fresh, seasonal blackberries and a hint of agave syrup for its sweetness. In the end, you'll have made a cocktail that is less than 200 calories.
