Loquats can be slightly tart depending on their ripeness. Adjust the amount of lime juice or add a tiny pinch of sugar to balance the flavors if needed. For a milder salsa, remove the seeds and membranes from the jalapeno pepper. For extra heat, leave some of the seeds in. This salsa is best served fresh. It can be stored in an airtight container in the refrigerator for up to 2 days, but the strawberries may soften slightly over time.
