Fresh basil is an aromatic culinary herb with tender green leaves, used in cocktails for its bright, peppery fragrance.
The leaf is here for the smell above the glass, so a substitute has to be something you can clap and drop in. Its peppery, anise-edged side is the part that shifts: another soft green herb moves the aroma, and a syrup moves the sugar with it.
Thai basil
Sturdier leaves, an aniseed edge and much less of the sweet pepper; it holds up to heat and reads as a different herb in a cold drink.
Basil syrup
Sugar with the herb already infused, and it sweetens as well as flavors, so a drink built for fresh leaves needs its sugar cut.
Stems in water on the counter, not in the fridge: basil is a tropical plant and cold turns the leaves black within a day. Wrapped loosely it lasts a few days. Blanching the leaves for a few seconds and shocking them in ice water fixes the green, which is how a basil syrup keeps its color.
