How to Make It
In a large bowl, toss the pears with the onion, salt and jalapeños. Cover and refrigerate overnight.
Drain the pears in a colander and rinse them. In a large saucepan, combine the pears with the remaining ingredients and bring to a boil. Simmer over low heat for 25 minutes, or until thickened. Let the pear relish cool. Serve cold or at room temperature.
