This is a five-minute refresher that lives up to its name: green syrup (likely anise-based) mixed with lemon squash, fresh lemon juice, soda water, and ice makes a bright, summery drink for two. All ingredients are shelf-stable except the lemon and ice, both of which every Charlotte grocer stocks year-round, so there's no special trip needed. The real cost driver is the green syrup itself—track down a Spanish or Mediterranean brand at Harris Teeter's international aisle or Publix (typically $5–8 a bottle)—but that bottle stretches across many drinks. It's genuinely fast and refreshing, reheats poorly but doesn't need to, and works as a same-night cooler on a hot afternoon; the caveat is that it's a single-serve refreshment, not a family meal, and only shines in warm weather.
