Ingredients Needed

Hazelnut syrup ingredients.
  • Sugar – To make the syrup, you will require granulated sugar. Additionally, natural sweeteners like honey and maple sugar can also be used.
  • Water – This ingredient is not fancy in any way. It is simply plain water, and the choice to use filtered or unfiltered water is entirely yours.
  • Hazelnut Extract or Hazelnut Liqueur – Hazelnut extract or hazelnut liqueur is used when making hazelnut syrup to provide a strong and authentic hazelnut flavor. While it is possible to use actual hazelnuts to infuse the syrup with their flavor, this method can be time-consuming and may not provide as strong of a flavor as using an extract or liqueur.

FAQS

How long does homemade hazelnut syrup last?

Homemade hazelnut syrup can be stored in the refrigerator for up to 3 weeks.

Can you freeze hazelnut syrup?

Hazelnut syrup can be stored in the freezer to prolong its shelf life, but due to its sugar content, it will not freeze completely. The syrup will remain in a semi-liquid state, but the cold temperature will prevent the growth of mold and bacteria.

Recipe Notes and Tips

  • Extend the shelf-life: After the syrup has cooled, stir in 1 ounce of vodka. This addition will help inhibit the growth of bacteria or mold, providing an additional 2 to 4 weeks of shelf-life.
  • Heating the syrup over the stove is not necessary. Instead, you can use very warm water from the tap to dissolve the sugar. Although it may take a little longer for the sugar crystals to dissolve, this method produces a more fluid syrup that is less thick.
  • How to know when the syrup has gone bad? If the simple syrup appears cloudy or has visible mold growth, it is a sign that it has gone bad and should be discarded.
  • Add more to your coffee bar! If you plan on adding this hazelnut syrup to your coffee bar you might also want to try Brown Sugar Syrup, Rosemary Simple Syrup, or even Strawberry Simple Syrup to make a Strawberry Latte.

Variations

  • Make a thicker syrup: The basic recipe for hazelnut syrup calls for a 1:1 ratio of sugar and water. If you prefer sweeter syrup, you can increase the amount of sugar, which will also extend its shelf-life since sugar is a natural preservative. However, this will also make the syrup thicker. Conversely, if you prefer a less sweet syrup, you can decrease the amount of sugar and increase the amount of water.
  • Infuse the syrup with spices: Create an infused syrup by adding spices, making it an excellent gift for foodies or mixologists. Mix cinnamon, vanilla, or nutmeg into the simple syrup and allow the mixture to heat for 10 to 15 minutes to fully infuse the flavors.
  • Use real hazelnuts: Swap the hazelnut extract for 1 cup of chopped hazelnuts. You’ll need to cook the mixture for a minimum of 10 minutes and then let it sit to cool for about 20 minutes. Next strain the syrup through a mesh sieve. Discard the remaining hazelnut pieces.
