This jalapeno simple syrup is exactly what you need to transform your beverages into something unexpected and extraordinary. I simmer fresh jalapenos with granulated sugar and water until it becomes a smooth, pourable syrup with concentrated flavor. It takes just 15 minutes and 3 ingredients to make this sweet, spicy, and versatile liquid.

There is not a single summer that has gone by without me making some kind of simple syrup. They are deliciously convenient and can liven up sparkling water. The capsaicin in the fresh jalapenos infuses into the syrup, creating a balanced heat that is warm rather than unbearable. If you love cordials but would prefer to stick to fruit-based flavors, try my peach simple syrup instead,  for a sweet more flowery flavor. 

My sister and I love indulging in a sneaky little homemade drink now and then, and usually an Italian margarita is our favorite. Recently, she commented that since we prefer staying in for a girls’ night, we should at least try to liven up our drinks. I totally agreed. The next time she came over, we used this jalapeno simple syrup in our frozen margarita cocktails. The combination of the lime and jalapeno was so sublime, we finished the jug before my husband even got to try it. Whoops. Ha!

🥘 Ingredients

This jalapeno simple syrup uses just 3 ingredients to create its unique flavor. This is what I use:

Fresh jalapenos: This gives my syrup its signature flavor and heat. I also keep a few slices aside to add to my jar after my syrup has cooked. 

Granulated sugar: I use white granulated sugar for a clean, neutral sweetness and appearance that does not overpower the jalapeno. Brown sugar yields a cloudy, slightly off-color syrup that may look unappealing to some people.

Water: I combine the water with the sugar for the classic simple syrup base.

🔪 How To Make

I use a small pot to make this syrup from start to finish. This is how I do it:

Prepare the jalapenos: I slice the jalapenos into rounds and set them aside.

Boil ingredients: Next, I combine my water, sugar, and jalapenos in a pot, stir slightly, and bring to a boil.

Simmer: Once boiling, I reduce the heat and allow the mixture to simmer for 10 minutes until the sugar is completely dissolved.

Strain the syrup: Then I pour the syrup through a fine mesh strainer, and into a sterilized glass jar, and allow it to cool.

Refrigerate: Once cooled, I add a few slices of fresh jalapenos and store them in the fridge for up to 1 month. 

📖 Variations

I was surprised at the different ways I could flavor this jalapeno simple syrup, without compromising on the key flavors. I recommend trying these 3 variations:

Serrano upgrade: I swap out the jalapenos for an equal amount of serrano pepper. This syrup is noticeably hotter, with a more complex flavor. I made this version for a friend of mine who has an impressive heat tolerance, and he loved it. 

Lime infusion: For a fresh citrus note, I add the juice of 1 lime and a few strips of zest into the pot with the jalapenos. This version is very refreshing over crushed ice and sparkling water. 

Mint boost: I chiffonade a few sprigs of fresh mint and add it to the syrup mixture as it simmers, which creates a cooling contrast to the jalapeno. Whenever I use this, I add a few more sprigs of fresh mint to liven up the flavors. 

🍽 Serving Suggestions

Whether I am using this jalapeno simple syrup in a cocktail or in a jug of sparkling water with cubes, I always make sure to serve it with other drinks or dishes that highlight the complex sweetness in this syrup. I recommend drizzling some of this simple syrup over a few slices of grilled pineapple to bring out the flavors in the fruit in a way you never expected. If using it in a beverage, make sure you have a plate of my vegan jalapeno poppers on the table too! 

I have already begun planning my menu for Cinco de Mayo, and have been experimenting with different dishes. My jalapeno popcorn will make its annual appearance along with something a bit different. Recently, I added some of this jalapeno simple syrup into my lemon popsicles, for a cold treat with a touch of unexpected heat. I was not sure if this combination would work, but all I can say is… WOW! Hopefully, I have time to experiment with a few other flavors too. 

🧊 Storing And ♨️ Reheating

Refrigeration: I store cooled syrup in a sterilized mason jar in the fridge for up to 1 month.

Freezing: This syrup is not suited to freezing, as the high sugar content prevents it from freezing properly.

Reheating: If the syrup has thickened too much after refrigeration, place the sealed jar in a bowl of warm water to loosen it up. I do not reheat the syrup directly as it will change the flavor.
