Sweet Onions

Directions

1. 1
   Preheat oven to 250 (not a mistake).
2. 2
   Peel onions and cut each in half through the stem end, then cut each half into quarters; cut the quarters in half crosswise; place onions into a bowl.
3. 3
   To the onions, add olive oil, balsamic vinegar, honey, and pepper; toss to coat onions well.
4. 4
   Pour onto a small baking sheet or into a 9-inch ovenproof skillet (the onions should be piled onto the pan, not spread in a single layer); set the bowl aside.
5. 5
   Cook the onions for a total of 3 hours; take them out every 30 minutes and transfer back to the bowl to mix thoroughly before rearranging on the baking sheet and putting back in the oven--this keeps any part of the onion slices from drying out and becoming crispy.
6. 6
   Will keep indefinitely in the refrigerator.
