What gin works best in this drink?
A classic London Dry gin is great here. If your gin is very floral, keep the basil moderate so it does not get too perfumey. If your gin is citrus-forward, it plays especially nicely with lime.
Can I make this without a cocktail shaker?
Yes. Use a mason jar with a tight lid. Muddle in the jar, add ice, shake hard, then strain into your glass.
How do I keep basil from tasting bitter?
Be gentle. You want to press and bruise the leaves, not shred them into a green paste. A quick muddle is enough to release aroma and flavor.
Can I make it less sweet?
Absolutely. Start with 1/2 ounce syrup, taste, then add more if needed. Also, club soda (not tonic) keeps it drier.
Is tonic water okay instead of club soda?
You can, but it changes the drink a lot. Tonic adds sweetness and quinine bitterness. If you use tonic, reduce the ginger syrup a touch and taste as you go.
What glass should I use?
Highball: more bubbles, lighter feel. Rocks glass: a shorter, stronger pour. Both are great, just pick your mood.
What is an easy non-alcoholic version?
Skip the gin and add extra club soda, or use a non-alcoholic gin alternative. The basil, lime, and ginger still bring plenty of “cocktail energy.”
