Step 1

Preheat oven to a high broil. Place an oven rack on the very top shelf just below the broiler element, leaving just enough space to fit a baking sheet. Optional: Line your baking sheet with foil for easy cleanup. Place jalapeños cut side down on the baking sheet and broil for 4-5 minutes, watching closely, until the outside of the jalapeños begin to blister and blacken. You want them ~50% charred. Remove from the oven and set aside to cool.

Step 2

In a blender, combine the water, passion fruit purée, agave nectar, lime juice, and cooled jalapeños. Blend on high until smooth with no chunks of jalapeño remaining. Taste and adjust as needed, adding more passion fruit or lime for tartness or more agave for sweetness.

Step 3

To enjoy, strain into a jar or pitcher to save for later use, or strain directly into serving glasses over ice. Leftovers keep for 2-3 days in the refrigerator or in the freezer for up to 1 month. This would also be delicious as popsicles!
