Charring red onions bring out a smoky sweetness in this versatile (and three-ingredient) jam recipe from Victor Albisu of Del Campo in Washington, D.C. Balsamic vinegar adds tang and a touch more sweetness for a condiment that's just as good spread onto sandwiches or used as the base for pizza as it is mixed into pasta.
We love the ease of broiling the onions. However, if you feel inclined to fire up the grill, Albisu loves the extra punch of smoke you’ll get on it.
