Every year, there's a frenzy around the first spring onions. And every year, the problem remains that their season is just too short. With this recipe from Oregon blogger Eva Kosmas Flores's beautifully styled new book, First We Eat, you'll capture the fleeting alliums by cooking them down with sherry vinegar to make a condiment that works just as well on toast as it does over an equally springy lamb chop.

Take it to the next level by serving the jam with fried spring onions or use any extras to make a spring onion martini.

Ingredients
  • ½ cup (1 stick) unsalted butter
  • 1 pound spring onions, thinly sliced
  • 3 tablespoons extra-virgin olive oil, divided
  • 1 tablespoon sherry vinegar
  • 3 tablespoons sugar
  • 1½ teaspoons flake kosher sea salt
Directions
  1. In a large skillet, melt the butter over medium heat. Add the onions and 1 tablespoon of the oil, and reduce the heat to low. Cook, uncovered, until the onions soften, about 10 minutes. Add the vinegar, sugar, salt and remaining 2 tablespoons of oil, and stir to incorporate. Cook until the onions turn deeply golden and fragrant, about 40 minutes, stirring every 10 minutes.
  2. Remove from the heat and allow to cool to room temperature before transferring the jam to a mason jar. Seal and refrigerate. Use or keep in the refrigerator for up to 1 month.
