- A small handful of fresh basil (about 5 g) – leaves and stems
- 1½ teaspoons granulated sugar
- 2 ounces cachaça or flavorful rum
- 1 ounce fresh squeezed lime juice
- 3 ounces passionfruit cocktail – you can find this on the top shelf of the bottled juice aisle at your supermarket or in any Latin grocery store or bodega
- 3 ounces good tonic water to top – I like Fever Tree
Aside from being delicious, the cool thing about this drink is that it is super easy to make, but it also involves several flashy-looking (but easy) bartending techniques.
Drop the basil into the larger half of a cocktail shaker, then add the sugar. Aside from adding sweetness to this enterprise, it is also abrasive, and will help break down the basil when you muddle it.
Cool Bartender Technique #1 – Muddle the basil. All this means is that you’ll mush the basil up with a stick — in my case, I use the billy-club-like pestle from my largest mortar and pestle. Smash the basil leaves up, and grind them up with your muddler (stick) and the sugar. After a minute or so of energetic muddling, the basil will have turned gloppy (a technical term) and dark green. Rattle your muddler against the sides of the cocktail shaker to knock off any basil or sugar that might be stuck to it.
Cool Bartender Technique #2 – Add the cachaça to the basil glop, and dry-shake it. Dry shaking means to shake ingredients without ice. In this case, a lot of the flavor of the basil is found in aromatic oils that you have liberated with your muddling. These oils aren’t water-soluble — in other words, they won’t mix easily with water-based ingredients. They are, however, extremely sociable in the presence of alcohol. (Aren’t we all?) By shaking the basil and cachaça together without any ice, the alcohol will have a chance to strip away the basil’s more sophisticated flavor compounds.
Once the basil oils have been suspended in alcohol, they will mix more readily with the rest of the ingredients. You can add the ice, now. Also add the lime juice and the passionfruit cocktail. (Shake the passionfruit cocktail, in case it has separated.) Seal the cap on your cocktail shaker, and shake the mixture enthusiastically.
Cool Bartender Technique #3 – Strain the passionfruit mixture over fresh ice in a tall glass. There are several ways to strain a cocktail. If you have shaken it in a two-piece Boston shaker, you can simply break the seal between the two halves, and carefully pour the liquid out from where the two halves meet. This will do a good job of keeping the old ice and any large blobs of basil mush from getting into your glass, but you might find yourself with a few more floating bits of basil than you want. I double down and pour the mixture through a mesh drain strainer — about $2 at any hardware store — which limits any green floaters to very small pieces of basil.
Depending on the size of your tall glass, and how much ice you’ve put in it, you might find that your passionfruit-basil mixture fills it almost to the top. In this case you might have to take one for the team and drink a vigorous sip of this highly flavorful drink to bring the surface level down a couple of inches from the top of the glass.
Finally, add three ounces or so of tonic water to the glass, and stir it gently, to add some effervescence to it. Garnish with one of the spent lime halves, and drink with a straw. It tastes fruity and sweet and sour, with funkiness from the cachaça, acid from the lime juice, and a lingering kiss of basil.
Highly recommended.
