  1. In a small saucepan, combine water, sugar of choice, and fresh rosemary sprigs. Make sure the sugar is spread evenly and the rosemary is submerged for the best results.
  2. Place the saucepan over medium-high heat. Once the mixture begins to boil, reduce the heat to maintain a gentle simmer. Let it bubble for about 5 minutes uncovered, ensuring the sugar dissolves completely. There’s no need to stir! This process helps to extract the rosemary flavor and helps your syrup have the right consistency.
  3. After simmering, turn off the heat and place the lid on the saucepan. This is where the magic happens! Let the syrup steep for at least 15 minutes. This step allows the rosemary flavor to become more pronounced and infuse the syrup thoroughly.
  4. Once the steeping is done, remove the rosemary sprigs. You can strain it through a fine mesh strainer if desired. Funnel the liquid into a glass jar or bottle.
  5. Before storing it in the fridge, allow the syrup to come to room temperature. Then, seal it in an airtight container. This not only extends the syrup’s shelf life but also ensures it retains its rich, herbal taste.
  6. Now, your homemade rosemary simple syrup is ready to elevate your drinks, desserts, or even savory dishes! Whether you’re adding it to a gin cocktail, drizzling it over a cake, or mixing it into a refreshing rosemary lemonade, the possibilities are endless.

Additionally, it can be brushed on freshly baked goods for an extra burst of moisture and flavor. And if you’re serving ice cream, a little drizzle of this syrup can make it an unforgettable dessert experience.

🥡 Storing Simple Syrup

Using a clean, airtight container or mason jar is ideal. Pour the cooled syrup into the container and ensure the lid is sealed tightly. This syrup is best kept in the refrigerator, where it can last for up to a month. The cold environment slows down any potential fermentation and keeps the syrup tasting its best.

To maintain the best quality, always use a clean spoon or funnel when pouring or using the syrup. Introducing foreign particles or contaminants can reduce the syrup’s shelf life and might introduce unwanted flavors. If you notice any signs of fermentation, such as bubbling, off-smells, or mold, it’s best to discard the syrup and make a fresh batch.

💭 Top Tips

Use Quality Ingredients: Opt for fresh rosemary sprigs over dried ones, as they provide a more vibrant and aromatic flavor profile. When it comes to sugar, while granulated sugar is the default choice, don’t shy away from experimenting with brown sugar or cane sugar to introduce different taste nuances.

Simmer, Don’t Boil: When heating your mixture of water, sugar, and rosemary, aim for a gentle simmer rather than a vigorous boil. A softer simmer ensures that the sugar dissolves seamlessly without any risk of caramelizing, which could introduce a burnt taste. Additionally, simmering helps to extract the rosemary flavor optimally, making your syrup richer in taste.

Adjust to Your Taste: Feel free to adjust the amount of sugar or rosemary to suit your preferences. If you prefer a stronger rosemary flavor, add a couple more sprigs of fresh rosemary or extend the steeping time. For a sweeter syrup, increase the sugar quantity a bit. 

Experiment with Variations: Rosemary simple syrup is just the beginning! Once you’re comfortable with the basic recipe, why not try other herbs or add-ins? Mint, ginger, or even a splash of lemon juice can give your syrup a unique twist. The beauty of homemade syrups is the freedom to customize them to your liking.

    This was an easy way to change my favorite Woodford Reserve cocktail – if fact, I don’t think I’ll go back to using unflavored simple syrup now. Thanks!
