Cut jalapeños in half. Scoop out the seeds and rinse the jalapeños in water (if you want a stronger spice level, see the paragraph above). Dry off the jalapeños and cut them into small pieces.
Add the cranberries, sugar, water, jalapeños, orange zest, and salt to a pot over medium heat. Cook, stirring frequently, until the mixture begins to boil.
Turn the heat to low and cook for 15-20 minutes, stirring occasionally. The cranberries will be broken down and the mixture will be thick and jammy.
Remove from the heat and transfer to a container. Cover and transfer to the fridge. Let the sauce cool completely. Enjoy!!
