Rosemary's reputation is almost entirely savory, which makes it an easy herb to overlook for drinks - but its piney, slightly sweet undertone actually works well in a simple syrup, bridging into cocktails, lemonade, and iced tea without tasting out of place.
Rosemary Simple Syrup
Prep time: 5 minutes | Cook time: 10 minutes, plus steeping | Makes: about 1 cup
Ingredients
- 1 cup water
- 1 cup granulated sugar
- 3 to 4 sprigs fresh rosemary
Instructions
- Combine the water and sugar in a small saucepan over medium heat. Stir until the sugar fully dissolves.
- Add the rosemary sprigs and bring the mixture to a gentle simmer. Simmer for 2 to 3 minutes, then remove from the heat.
- Let the rosemary steep in the syrup as it cools completely, at least 30 minutes - the longer it steeps, the stronger the rosemary flavor.
- Once cooled and steeped to your liking, strain out the rosemary sprigs and transfer the syrup to a clean, sealed jar or bottle.
Notes
This syrup keeps in the fridge for about 3 to 4 weeks in a sealed container.
How to Use It
- Lemonade: Stir a tablespoon or two into a glass of fresh lemonade for an herbal edge that pairs surprisingly well with the citrus.
- Iced tea: A small amount stirred into black or green iced tea adds complexity without being overpowering.
- Cocktails: Rosemary syrup is a natural fit in gin-based cocktails, whiskey sours, or a simple vodka soda, where its piney note complements botanicals already present in gin especially well.
- Sparkling water: A splash in plain sparkling water with a squeeze of lemon makes a quick non-alcoholic drink.
- Sweetening baked goods: Use in place of plain simple syrup when brushing cake layers for a subtle herbal note.
Adjusting the Strength
Rosemary's flavor comes through fairly quickly in a hot syrup, so if you want a more subtle result, strain the rosemary out after only 10 to 15 minutes of steeping rather than the full 30 minutes. For a more intense syrup, let it steep for a couple of hours, or even overnight in the fridge, before straining.
Variations
- Rosemary citrus syrup: Add a few strips of lemon or orange peel along with the rosemary while simmering.
- Honey version: Substitute honey for half the sugar for a rounder, less sharply sweet syrup - dissolve the honey off the heat once the water and sugar mixture has cooled slightly, to preserve more of the honey's flavor.
- Black pepper rosemary syrup: Add a few cracked black peppercorns for a more savory, cocktail-forward version.
