Gently wash and dice the fresh peaches into small, uniform pieces (about 1/4 inch cubes).

Finely mince the red onion. For a milder flavor, you can soak the minced onion in cold water for 5 minutes, then drain well.

Carefully mince the jalapeño. For less heat, ensure all white pith and seeds are fully removed before chopping.

In a medium mixing bowl, combine the diced peaches, minced red onion, minced jalapeño, and chopped cilantro.

Squeeze the juice from the fresh lime over the mixture. Add the salt and black pepper.

Gently fold all ingredients together until everything is evenly coated with the lime juice. Taste and adjust seasonings, adding more salt or lime juice if necessary.

Cover the bowl and refrigerate the salsa for at least 15 minutes to allow the flavors to meld before serving.
