Technique
Making Simple Syrup
Simple syrup is sugar dissolved in water. That's it. But the ratio matters, the temperature matters, and the variations — infused with rosemary, lavender, cinnamon, or citrus — dramatically expand what you can do with a single base technique. Five minutes of work produces two weeks of better drinks.
What's actually happening
Simple syrup integrates sweetness smoothly into cold drinks in a way that granulated sugar cannot. Because it's already dissolved, it distributes evenly without creating gritty texture or requiring long stirring to incorporate.
When to reach for it
Whenever a recipe calls for sweetener. Also as a base for infused syrups — add herbs or spices while the mixture is warm, steep, strain, and bottle.
Where people usually go wrong
- Boiling the syrup. Bring to a simmer just until the sugar dissolves — boiling concentrates the mixture and can produce a slightly different flavor.
- Not letting it cool before using. Hot syrup changes the temperature balance of a cold drink.
- Using it past its window. Simple syrup keeps in the refrigerator for two weeks before it starts to degrade. Label the bottle with a date.

The tool I reach for
Glass Swing-Top Bottles
A 500ml swing-top bottle holds a standard batch of simple syrup and keeps it fresh. I keep two — one 1:1, one 2:1 rich.

Questions I hear a lot
How do I know when my simple syrup is done?
The syrup is done when the sugar is fully dissolved and the liquid is clear — typically 2-3 minutes of gentle simmering. Don't boil; a simmer is enough. If you can't see any sugar granules at the bottom of the pan and the liquid is transparent (not cloudy), it's ready. Remove from heat immediately and let it cool completely before bottling.
What happens if I use simple syrup before it cools?
Adding hot syrup to a shaker with ice accelerates ice melt dramatically, over-diluting the drink and warming it before you've had a chance to shake it properly. The temperature balance of a cold cocktail depends on all non-ice components being at room temperature or below. Always let syrup cool completely — or refrigerate it — before using.
How do I make infused simple syrup?
Make the base syrup, then add your infusing ingredient (rosemary sprigs, lavender buds, cinnamon sticks, citrus peel) while the syrup is still warm off the heat. Cover and steep for 20-30 minutes, tasting every 10 minutes — the flavor extracts quickly and can become overwhelming if you steep too long. Strain through a fine mesh, bottle, and refrigerate. Infused syrups typically keep for about 1 week.
