Making Herb Infused Syrups
An infused syrup bridges the gap between raw botanical punch and a rounded, drinkable flavor. It is a fundamental tool for leveling up coffee, tea, or mixed drinks without needing store-bought extracts.
Balance is everything
Use woody herbs like rosemary or thyme for longer infusion times, and delicate herbs like basil or mint for shorter windows.
- small heavy-bottomed saucepan
- fine-mesh strainer
- clean glass jar or bottle
- silicone spatula
What goes in.
- 1 cupgranulated white sugar
- 1 cupwater
- 1 bunchfresh herbs (rosemary, mint, basil, or sage)
Respect the simmer
Do not boil the herbs. The water must be off the heat before adding them to ensure the heat gently draws out essential oils without scorching the leaves.
The method.
Dissolve the sugar
Combine water and sugar in the saucepan over medium heat. Stir until the liquid is perfectly clear and there is no grit at the bottom.
Add the herbs
Remove the pan from the heat immediately. Toss in the herbs, ensuring they are fully submerged, and cover the pan with a lid.
Steep
Let the mixture sit for 20 to 30 minutes. Taste after 15 minutes; if you want a deeper flavor, keep going. If it tastes grassy, pull the herbs out.
Strain and store
Pour the syrup through a fine-mesh strainer into a clean glass jar. Discard the spent herbs.
Other turns to take.
Spiced Herb
Add a cinnamon stick or three crushed cardamom pods alongside the herbs for extra complexity.
Citrus Herb
Add a strip of lemon or grapefruit zest during the steeping phase for a brighter profile.
When it doesn't go to plan.
Clean your storage jar with boiling water before use to help the syrup stay fresh for up to two weeks.
If using thin herbs like mint, bruise the leaves slightly with your hands before dropping them in to release the oils.
Always use a heavy-bottomed pan to prevent the sugar from scorching while it dissolves.
The ones that keep coming up.
Can I use honey instead of sugar?
Yes, but use honey at the very end. Once the water is heated and removed from the flame, stir the honey in so you don't cook away its raw properties.
How do I know if the syrup has gone bad?
Look for any signs of cloudiness or mold on the surface. If it smells fermented or loses its clarity, discard it.
