Book Report Apr 22, 2015

Your imagination's the only thing that will limit the use of this jam in all sorts of savory applications: eggs Benedict, grilled cheese sandwiches, layered dips or salads.

Use a mandoline to slice the onions, if you have one.

Make Ahead: The jam can be refrigerated in an airtight container for up to 2 weeks.

Directions

Heat the oil in a medium skillet over medium-low heat. Add the sliced onions and stir to coat; cook until they begin to soften and turn translucent but do not brown, 10 to 15 minutes.

Stir in the sugar and vinegar; reduce the heat to the low or medium-low (to maintain a constant, slow bubble) and cook, stirring occasionally, until the liquid evaporates entirely, creating a jam that is thick and sticky, about 45 minutes to 1 hour. Remove from the heat.

Stir in the salt. Let cool, then transfer to an airtight container. Refrigerate for up to 2 weeks.
