Water: Water is the base of this rosemary simple syrup recipe, acting as the medium through which the flavors of the sugar and rosemary are extracted and combined. Make sure to use clean, filtered water for the best results.
Sugar: Sugar provides the sweetness that characterizes this syrup. While granulated white sugar is a common choice, you can also explore variations:
- Coconut Sugar or Brown Sugar: Gives the syrup a deeper, caramel-like taste.
- Cane Sugar: Offers a hint of molasses flavor, making the syrup slightly richer.
- Honey or Agave: Natural sweeteners that can be used for a different kind of sweetness. Keep in mind, the syrup’s consistency might slightly differ if honey or agave is used.
Sprigs Fresh Rosemary: Fresh rosemary sprigs are the star of the show! They infuse the syrup with a fragrant, herbal aroma and flavor. When choosing rosemary, opt for fresh over dried, as fresh sprigs deliver a more vibrant taste.
Substitutions and additions:
- Mint: If you’re in the mood for a different herbal note, mint is a refreshing alternative.
- Ginger: For a spicier kick, ginger can be a great addition or alternative.
- Lemon or Lime: Adding citrus zest or juice can introduce a zesty twist to your syrup. Perfect for summer drinks!

Frequently Asked Questions
Can I use dried rosemary instead of fresh?
While fresh rosemary sprigs are recommended for a vibrant flavor, dried rosemary can be used in a pinch. However, adjust the quantity since dried herbs are more potent than fresh.
Is it possible to make a sugar-free version of rosemary simple syrup?
Yes, you can use a sugar substitute like stevia or erythritol. However, the flavor profile and sweetness level may vary, so adjust to taste.
How can I make my rosemary simple syrup thicker?
For a thicker consistency, reduce the water amount or increase the simmering time to allow more water to evaporate.
Can I add other herbs or spices to my rosemary simple syrup?
Absolutely! Feel free to combine rosemary with other herbs like mint or thyme, or even spices like ginger, for a unique flavor twist.
What’s the difference between using white sugar, brown sugar, and cane sugar in the syrup?
White sugar provides a clean, sweet taste; brown sugar adds a molasses-like depth; and cane sugar offers a slightly earthy sweetness. Each one can bring a distinct flavor nuance to your syrup.
If my syrup crystallizes, what can I do?
If your syrup crystallizes, simply reheat it gently in a saucepan until the crystals dissolve. To prevent crystallization, ensure the sugar is fully dissolved during the initial cooking process.
