Look for jalapeños that say “en escabeche” on the label. This means they are pickled in a liquid of vinegar, onions and carrots. Some brands may not include this on the label, so just check the ingredient list on the can.
Try these warm. Prepare as directed; place on broiler pan in between indents to prevent the stuffed jalapeños from rolling while baking. Bake at 350°F 10 minutes or until warm. Cool slightly before eating.
The small end of a small melon baller works wonderfully to remove the seeds and hollow out the inside of the chiles.
