As promised, onion jam to go with that fig tart.
I fell in love with onion jam at a sausage party. And seeing that in writing just now made me laugh out loud a little bit. Let me explain. When my best childhood friend turned thirty last year, there was a party in his honor and homemade sausage was the main attraction. It was a literal sausage party. Although, now that I think about it… I’m totally being a 14-year-old dude right now. My apologies!
Anyway, as I was saying, there was a very innocent looking jar of onion jam at this party, alongside the platters of grilled sausages. I had a feeling about that jam, and it did not disappoint. Onion jam is a sausage’s best friend.
Making onion jam requires little more than onions and patience. Onions, caramelized to max, are the perfect condiment – sweet and savory and super flavorful. You’ll want to put it on just about everything.

makes 1 cup **recipe can easily be doubled
2 pounds yellow onions, about 7-1/2 cups sliced
1 tablespoon olive oil
1 teaspoon kosher salt
1/2 teaspoon freshly ground pepper, or to taste
1 teaspoon red wine vinegar
Cut the stems off the onions. Slice each onion in half through the root end. Lay each onion half cut-side down and slice it, toward the root, into slices about 1/4-inch thick.
Heat a 5-to 7-quart heavy bottomed pot over a medium-high flame. Add the olive oil and heat until it’s shimmering. Add the onions, salt, and pepper and stir to coat the onions with the oil. Saute the onions for 10 to 15 minutes, stirring occasionally, until the onions have lost their gloss, the bottom of the pan is getting dark in areas, and the edges on the onions are beginning to brown. Turn the flame to low, cover the pot, and cook for 20 minutes.
Uncover the pan, stir the onions, scrape any dark flavorful bits from the bottom of the pan, and continue to cook, uncovered, for 1 hour more. Stir the onions occasionally, especially toward the end of cooking time, to prevent burning. The onions are ready when the liquid has evaporated and the onions are dark, translucent, and jammy. Stir in the vinegar and allow to cool. The onion jam will keep int he refrigerator for 2 weeks, or in the freezer for 1 month.
