For a milder flavor, remove the seeds and membranes from the jalapeño before slicing. If you prefer a different sweetener, you can substitute honey or agave nectar for the maple syrup. Adjust the amount to your desired sweetness level. Feel free to experiment with other spices, such as a pinch of red pepper flakes, a star anise, or a few black peppercorns, to customize the flavor profile. Ensure the jar and lid are properly sterilized before use to prevent spoilage. These pickled carrots are a delicious addition to tacos, spring rolls, and even as a vibrant topping for grilled meats or fish.
