Jalapeno Simple Syrup is an easy, spicy-sweet way to add heat to your mocktails. With just 3 ingredients and less than 15 minutes of your time, you can enjoy fun drinks whenever you want. I recommend keeping a jar in your fridge at all times!

If you are looking for a spicy mocktail, this Jalapeno Margarita Mocktail is the perfect addition to Jalapeno Simple Syrup!

I have an addiction to simple syrups! On any given day there are at least three flavors taking up space in my refrigerator. I love them for sweetening my daily cold brew coffee and my nightly mocktail. They are also perfect in teas, lemonade, craft cocktails, etc. I have even been known to throw a little in my pineapple Greek yogurt!

What is Simple Syrup?

Simple syrup is made with equal parts water and sugar. The sugar is dissolved into the water over medium-high heat to become a thick, sweet syrup.

This recipe uses slices of fresh jalapeno (with it’s seeds) to make an infused simple syrup. When added to a drink it gives your lips a tingly, warm sensation in the front and then the sweet jalapeno taste in the back.

How Spicy is This Jalapeno Simple Syrup?

If I had a dollar for every time I am asked this question, I would be a millionaire! This is hard to answer because it depends on how individuals handle spice. Me personally, I do not handle spice very well but I love spicy cocktails and mocktails.

Keep in mind three things, (1) sugar will cut through some of the spiciness, (2) most drinks will only call for a small concentrated amount (an ounce or two) of simple syrup, and (3) the heat of each jalapeno will vary.

I prefer my jalapeno syrup to have a half cup of sliced jalapenos which is around 3 jalapenos. You can adjust this up or down based on your taste preferences. I like to tell people it is mostly heat but not hot, especially once it is added to your favorite drink.

Ingredients You Will Need:

  • Water: Room temperature tap water works great in this recipe.
  • Granulated Sugar: You can use cane sugar or brown sugar as well. I use whatever I have on hand at the time.
  • Jalapenos: Fresh jalapenos are best but you can also use serrano peppers or any other variety you prefer. Cut them into half inch slices and keep as many of the seeds as possible (that is where this syrup gets it’s heat).
Ingredients for Jalapeno Simple Syrup: sugar, water, and sliced jalapenos with their seeds.

How to Make Jalapeno Simple Syrup

  1. Boil together the water and sugar in a small saucepan.
  2. Add the jalapeno slices and simmer over medium-low heat for about 10 minutes, or until the syrup thickens.
  3. Cover the saucepan with it’s lid and remove from the heat.
  4. Cool the simple syrup to room temperature.

How to Store Jalapeno Simple Syrup

It will need to be stored in an airtight container or glass jar. The jalapeno syrup will last for about a month in the refrigerator, that’s if you don’t use it up quicker than that.

If you prefer a more mild syrup, you can use a fine mesh strainer to remove the jalapenos and seeds. I just pour mine into the jar as is to keep the jalapeno syrup infusing while it is in the refrigerator. Once the syrup is gone I eat the candied jalapenos. SO GOOD!

PRO TIP: Freeze the jalapeno simple syrup into cubes and in a plastic bag. They will last up to a year in the freezer and double as an ice cube!

Frequently Asked Questions (FAQ’s) About Jalapeno Simple Syrup

How can I adjust the heat level of the Jalapeno Simple Syrup?

Every pepper is different and the heat levels will vary in your jalapeno syrup. To make it spicier you can add more jalapeno slices or use a different type of hot pepper (serranos, habaneros, etc.). To make it less spicy you can use less jalapenos, steep/simmer the syrup for less time, or remove them from the liquid before storing in the refrigerator. I don’t recommend reducing the spice because once you add it to your drink you will likely lose the jalapeno flavor all together. Remember it will balance out once it has been mixed in with other liquids.

How long does Jalapeno Simple Syrup last?

If stored properly in the refrigerator, jalapeno syrup can last up to one month. Just make sure it is in an airtight container or jar. Before using check for foul odors, mold around the rim of the container, and an overly cloudy syrup. This may mean your syrup is no longer fresh and safe to consume.

How much Jalapeno Simple Syrup should I use in my drink? 

A great rule to follow is for every 8 to 10 ounces of liquid add 1 ounce of simple syrup. Test your drink before adding more simple syrup, as adding too much can make for a super sweet drink.
