History

Friggione is the everyday Bolognese countryside dish that arrived in the city in the 19th century through the contadino kitchens. The Accademia Italiana della Cucina deposited the legal recipe with the Camera di Commercio of Bologna on 23 January 2009: 1kg white onions, 500g peeled tomatoes, sea salt, no garlic, no herbs, slow-cooked uncovered three hours over very low heat until the onions break down into a dark, jam-like glaze. The 2009 deposit settled the long Bolognese kitchen argument over whether olive oil or lard was canonical (the answer: olive oil). Trattoria di Via Serra, Da Cesari and Diana serve it as a side; Tamburini sells it by the tub at the counter.

Yield 6Hands-on 15 minTotal 3 hr 30 minDifficulty Easy

Ingredients

  • 1kg white onions, very thinly sliced
  • 500g peeled San Marzano tomatoes, hand-crushed
  • 3 tablespoons extra virgin olive oil
  • 15g sea salt
  • 1 teaspoon caster sugar (only if the tomatoes are not sweet enough)

Method

  1. Mix the sliced onions with the salt in a deep bowl. Cover and rest 2 hours; the onions will release liquid and soften.
  2. Heat the olive oil in a heavy casserole over very low heat. Add the onions and their liquid. Cook uncovered 90 minutes, stirring every 15 minutes, until very soft and pale gold.
  3. Add the crushed tomatoes (and the sugar only if needed). Continue cooking uncovered over very low heat 90 minutes more, stirring every 10 minutes.
  4. The finished friggione should be dark mahogany, jam-like and oil-glossy. There should be no visible liquid.
  5. Serve warm or at room temperature with bollito misto, grilled meats, polenta or as a tigella filling.

Tip from the editors. Patience is the only technique; pushing the heat past medium-low and the onions burn. The two-hour onion salt-rest is non-negotiable.
