🌶️ Ingredients
A few things to note about what you’ll need:
- Water – For the freshest flavor and to avoid bacteria growth, use distilled water or filtered water.
- Sugar – Typically, bar syrups are made with granulated sugar, but feel free to use raw sugar or cane sugar.
- Jalapeno – You know your heat tolerance better than anyone. Use more or less of the spine and seeds to adjust the spiciness.

📖 How to make (step-by-step photos)
1️⃣ Step One: Slice jalapeño
With a sharp knife, carefully cut off the jalapeño stem and slice the jalapeño into quarters. If you can handle the extra heat, leave the inner membrane and seeds be. For a milder syrup, scoop out the membrane and seeds before starting your infusion.

2️⃣ Step Two: Infuse simple syrup
Add the water, sugar, and jalapeño pieces to a small saucepan. Bring the liquid to a boil, lower the heat to a simmer, and simmer until the sugar dissolves and the mixture thickens into a syrup (about 5 minutes). Remove from the heat. Remove the jalapeño pieces from the syrup and discard.

3️⃣ Step Three: Cool and store
Let the syrup cool completely to room temperature before straining into a sterilized glass jar and storing it in the fridge for up to 2 weeks.

❔Questions + quick tips
- Adjusting the heat – Most of the spicy hot flavor is packed in the seeds and spine. Leave them intact if you like things super spicy, or remove them for a milder flavor. You can also leave the peppers in the simple syrup as it cools to infuse more heat.
- Pepper variations – Another way to turn up the heat is by using a different hot pepper like serrano peppers or habanero peppers. Use anything hotter at your own risk!
- Using it to rim glasses – Add a salt or sugar rim to your serving glasses by dipping the edge of the glass in the sticky syrup and then in salt or sugar.
It’s best to use fresh jalapeno peppers to make spicy simple syrup. Pickled jalapenos have a distinct pickled taste that doesn’t mesh well with simple syrup.
Absolutely. Swap the sugar for honey to make simple syrup without any refined sugar. You can also use coconut sugar, agave, or date sugar.
