Why it matters
Syrup is the cheapest thing on a drink station to get right and the most common thing to get wrong. Granulated sugar does not dissolve properly in a cold drink, so anything sweetened at the glass with sugar is grainy at the bottom and thin at the top. Making syrup instead moves that problem into a saucepan once a fortnight. The ratio you choose also decides how much water you are adding along with the sweetness, which matters a great deal in a drink that already has ice in it.
The steps
Pick the ratio for the job
One part sugar to one part water by volume is simple syrup — easy to pour, and it dilutes as it sweetens. Two parts sugar to one water is rich syrup: sweeter per ounce, thicker, and it adds about half as much water for the same sweetness. Rich syrup is the better default for anything served over ice.
Measure by volume and stop worrying
Bar syrup is conventionally measured by volume rather than weight, and the tolerance is wide. A cup of sugar to a cup of water works with any measuring cup in the house.
Heat only until it goes clear
Warm the water, add the sugar, stir until you cannot see any crystals and the liquid turns from cloudy to transparent. That is the whole cooking process. Boiling it drives off water, concentrates the syrup unpredictably, and pushes it toward crystallizing later.
Steep flavorings off the heat
Herbs, spices, citrus peel and tea all go in once the pan is off the burner. Anything held at a simmer extracts the harsh compounds along with the pleasant ones — this is why cooked mint tastes like hay and cooked basil goes olive-colored.
Strain while it is still warm
Warm syrup passes through a sieve easily; cold syrup takes several minutes and leaves a lot behind on the solids. Do not press the solids — pressing pushes fine particles through, and those are what settle out in the bottle later.
Cool it fully before bottling
Warm syrup in a sealed bottle throws condensation onto the inside of the neck, and that thin layer of water on top of a sugar solution is where trouble starts. Room temperature first, then the refrigerator.
Label it with what it is and when you made it
Every clear syrup looks like every other clear syrup after four days. A strip of tape with a name and a date takes five seconds and prevents the whole problem.
Common mistakes
- Boiling the syrup to make it thicker. What you are actually doing is evaporating water and raising the sugar concentration past the point where it stays in solution, which is why that batch grows crystals a week later.
- Adding delicate flavorings at the start of the heat. Citrus peel, mint and basil all lose their fresh character within a minute of simmering and pick up a cooked note instead.
- Storing it at room temperature because it is mostly sugar. Syrup keeps far better cold, and the published cold-storage guidance is the right reference rather than an assumption about sugar being self-preserving.
- Making a quart of a flavored syrup you have never tried. Steeped syrups vary a lot; make a cup, live with it for a week, then scale the one you actually reach for.
