💧Ingredients & tools
Here’s what you’ll need to make fresh lemongrass infused simple syrup from scratch:
- Water – As the water and sugar simmer, the liquid will thicken into a syrup. To avoid bacterial growth during storage, use filtered or distilled water.
- Sugar – Granulated sugar or caster sugar is best for syrups, as the sugar granules are tiny and dissolve quickly.
- Lemongrass Stems – Fresh lemongrass adds subtly sweet and citrusy flavor to anything you add it to. No substitutions here!
- Recommended tools – You’ll need a small to medium saucepan, and an airtight glass jar.

🥣 How to make (step-by-step photos)
Step One: Cut lemongrass stems
Rinse your lemongrass stems with cool water. Then, cut the stems into 1/2 inch pieces. Set the pieces aside.
Step Two: simmer lemongrass syrup
Combine the water, sugar, and cut lemongrass stems in a small saucepan and heat over medium-high heat until water begins to boil. Then reduce the heat to a simmer and cook until the sugar dissolves and the syrup starts to thicken.

Step Three: Cool and store
Once the syrup thickens, remove the saucepan from the heat and let cool. Once cooled completely, pull out the lemongrass peels and pour the syrup into a glass storage container. Store it in the refrigerator for up to two weeks, OR pour your lemongrass simple syrup into ice cube trays and freeze for up to six months.
