Jigger or measuring spoons: For accurate measurement of gin, syrup, and tonic.
Cocktail shaker (optional): If I want to quickly combine the gin with the syrup before adding tonic.
Bar spoon: For gentle stirring, keeping the carbonation in the tonic.
Highball glass: A tall glass provides enough space for ice and garnishes.
Strainer (if using a shaker): To pour without shaking up the herbs or ice too much.
Citrus zester or peeler: For making a lemon or lime twist for garnish.
Fine mesh strainer (optional): If infusing my own lavender syrup and want a clear drink.
Ice cube tray: To make plenty of fresh ice for serving.
