The sweet & sour red onion jam recipe featured in Milk Bar Life, by Christina Tosi.
Ingredients
- 4 small red onions
- 2 Tbsp vegetable oil
- 1/2 cup sugar
- 1 cup rice wine vinegar
- 2 tsp kosher salt
Instructions
- Peel the red onions and thinly slice into rings; use a mandoline if you've got one.
- Heat the oil in a medium skillet over medium-low heat. Add the sliced onions and sweat until they begin to soften and turn translucent but do not brown, 10 to 15 minutes.
- Add the sugar and vinegar and cook over very low heat until the liquid evaporates entirely and the jam is thick and sticky, about 10 minutes.
- Take the jam off the heat and stir in the salt.
- Portion the jam out into jars. Keep refrigerated and eat within two weeks.
