Ingredients
Method
- Pull a double shot of espresso and let it cool for 3 to 5 minutes. Hot espresso makes the tonic foam over.
- Fill a tall glass with ice.
- Pour in the cold tonic water slowly so it keeps its fizz.
- Add any syrup or citrus now.
- Hold a bar spoon upside down just above the tonic and pour the espresso slowly over the back of it. The coffee will float in a dark layer on top.
- Serve right away and stir gently before drinking.
