Infusing Simple Syrups

Simple syrup is a one-to-one ratio of granulated sugar and water, simmered until the sugar dissolves. Infusing it requires nothing more than adding aromatics—herbs, spices, or citrus peels—to the hot liquid and letting them steep until the flavor matches your intent.

Before you start

Balance is the only rule.

Keep your heat low to avoid caramelizing the sugar, which changes the profile from bright and neutral to deep and toasted. Start with fresh, firm ingredients and strain them out completely to prevent fermentation.

  • small heavy-bottomed saucepan
  • fine-mesh sieve
  • glass jar with a lid
Ingredients

What goes in.

  • 1 cupgranulated sugar
  • 1 cupwater
  • 2-3 sprigsfresh herbs (mint, basil, or rosemary)
  • 2 stripscitrus peel (lemon, lime, or orange)
The key technique

Control the infusion

Delicate herbs need only 15 minutes to impart flavor before they turn grassy. Spices and citrus can sit for hours or even days for a punchier result.

Step by step

The method.

  1. Combine

    Place the sugar and water in the saucepan over medium heat.

  2. Dissolve

    Stir occasionally until the liquid turns completely clear and no grit remains at the bottom of the pan.

  3. Infuse

    Remove from heat immediately. Add your aromatics, cover the pan, and let it sit for at least 15 minutes.

  4. Strain

    Pour the mixture through the sieve into your jar. Discard the spent herbs or peels.

  5. Store

    Seal and refrigerate. Use within two weeks.

Variations

Other turns to take.

Spiced

Add one cinnamon stick or a teaspoon of black peppercorns during the heating process for a biting, warm finish.

Floral

Steep dried lavender or hibiscus buds for exactly 10 minutes to avoid a soapy or overly bitter aftertaste.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Use a vegetable peeler for citrus strips to avoid the bitter white pith.

Tip

If using woody herbs like rosemary, lightly bruise them with the side of a knife to release oils before adding.

Tip

If your syrup becomes cloudy, you have likely left the aromatics in too long; use it quickly.

Questions

The ones that keep coming up.

Can I use brown sugar instead?

Yes, but it adds a molasses note that will overpower delicate herbs like mint. Save brown sugar for spices like ginger or cinnamon.

Why did my syrup crystallize?

You either boiled it too long or added too much sugar. Keep the heat low and stick to the 1:1 ratio.
