This jalapeño simple syrup is the perfect way to add a spicy kick to any cocktail or mocktail. It contains just 3 ingredients, is super easy to make, and can be used  wherever you'd normally use simple syrup.


Units Scale
  • 1 small jalapeño pepper, sliced into rounds
  • 1/2 cup water
  • 1/2 cup turbinado sugar (can also use granulated white sugar)


  1. Add sugar and water to a saucepan over medium heat and stir well until sugar is dissolved. 
  2. Bring to a boil, add sliced jalapeños, and continue boiling for 3 minutes.
  3. Turn off the heat and let the syrup sit for 30 minutes.

  4. Pour the mixture through a fine mesh strainer into a heat safe container, and discard jalapeños and seeds. 


Makes about 1/2 cup (4 oz) of simple syrup.

If you want extra spice, skip straining the jalapeños out of the syrup. They will continue to infuse the syrup over time, adding spiciness. You can also use serranos instead of jalapeños for a seriously spicy syrup. Of course, be sure to strain before using in a cocktail. 

If you want to cut down on the spice but still keep some jalapeño flavor, remove the seeds and the membrane of the pepper, which is where most of the heat resides.

Storage: you can keep the syrup in a mason jar in the fridge for up to a month, or you can freeze the simple syrup in an ice cube tray and keep frozen for up to 3 months. To thaw, move to a glass and leave at room temperature until melted, or microwave for 15-20 seconds.

Sugar: You can also use white sugar or turbinado sugar.
