In a small saucepan, combine 1 cup of water, honey (or sugar), and sliced jalapeños.
Heat over medium until the sugar dissolves (don’t boil). Let it steep for 5 minutes for a intense kick.
Strain the mixture to remove jalapeño slices (or leave them for extra spice). And set aside.
In a large pitcher, combine lemon juice, jalapeño syrup, and the remaining 3 cups of water.
Stir well and adjust sweetness if needed.
Serve over ice, and Enjoy!
Notes
Adjust the heat level by removing the jalapeño seeds and inner ribs for a milder taste or keeping them intact for extra spice. Letting the syrup steep longer also intensifies the heat.
Sweetener options include sugar, honey, maple syrup, or brown sugar. For a different twist, you can also try agave nectar.
Make-ahead tip: Prepare the jalapeño syrup and fresh lemon juice in advance, store them separately, and mix when ready to serve for the freshest taste.
Storage: Keep in the refrigerator for up to 3 days or freeze for up to 2 months. Thaw in the fridge overnight or submerge in cold water.
Serve chilled—reheating is not recommended to preserve the fresh lemon flavor.
