After finding a great deal on jalapenos, I decided to make a bunch of different recipes! I worked my way through them all, removing the pith and seeds. After realizing just how much food I was throwing away, I decided to use those pepper guts to infuse a simple syrup.

This sort of approach is key in your zero waste kitchen! The pith and seeds still have so much flavor and heat – they make this simple syrup hot! Don’t worry – you don’t have to do it this way, though. You can absolutely use a regular jalapeno instead if you prefer.

Ingredients

Storing Suggestions

Once the syrup has cooled to room temperature, strain out the pepper pieces and store the spicy & sweet syrup in an airtight container in the fridge. You can safely store the syrup in the fridge for 3–4 weeks.  Don’t forget to date your container! 

Tips & Variations

  • If you are working on other jalapeno recipes, like dehydrating them or making this jalapeno sugar, don’t waste a jalapeno! Use the seeds and pith from 2-3 jalapenos (approximately ¼ cup) instead.
  • For a thicker, rich simple syrup, increase the sugar to 2 cups. 
  • Make a double batch. Simple syrup recipes are so easy to double because they use equal parts water and sugar. Just double everything or use the multiplier in the recipe card to make a big batch for your next party!
  • If you prefer a more complex flavor, consider replacing the cane sugar with brown sugar.
  • Jalapenos are spicy! Wear gloves or avoid touching your eyes or other sensitive areas.
  • For a milder syrup, use half of a pepper.
  • Peppers vary in heat, so taste and adjust the heat level as needed to get the perfect balance. You can always add an extra 1/2 cup of sugar and water and reheat it if your syrup is too spicy.
  • The membranes and seeds are hot! I used the pith and seeds from 3 jalapenos, and this syrup was spicy!
  • For a spicier syrup, add a second pepper or more of the membranes.
  • This particular recipe would taste lovely with fresh herbs, like a little mint or lemon balm.

FAQs

How do you use jalapeno simple syrup?

Simple syrup has a couple uses!  Most of the uses are drink-related, either making cocktails or mocktails.  However, you can use this as a drizzle over some savory or sweet recipes as well.

For example, you can brush it on your cake layers before icing to lock in moisture and add a little heat. It could even be used to candy bacon for a sweet-salty-spicy flavor
 experience spice lovers will absolutely love!

What can you do with leftover jalapeno seeds and membranes?

There are quite a few things you can do with leftover seeds. The simplest way to preserve them is to dry the seeds and save them to plant in the spring.

You can also use them to infuse flavor and the perfect amount of heat into other recipes. Try steeping jalapeno pieces into a standard simple syrup for a spicy kick. You could also add them to vinegar to add a little bit of heat in your homemade salad dressings.

How long does jalapeno simple syrup last?

Simple syrups can typically last for about a month, assuming the container is nice and clean. When you add other ingredients like fresh jalapeño slices
 or mashed fruit, that timeline shrinks as the fresh ingredients can go bad. Simple syrup made with fresh jalapeños can typically last about 3 weeks, so you can make it once and use it to add a delicious jalapeño flavor to your drinks for weeks!
