Ingredients

  • 1 lb small red onions or 1 lb shallot, peeled and cut in halve
  • 2 tablespoons olive oil
  • 1 stick celery, finely chopped (optional)
  • 1 garlic clove, finely chopped
  • 1 teaspoon fresh rosemary, finely chopped
  • 1 tablespoon concentrated tomato paste (puree in the UK)
  • 3 tablespoons cider vinegar
  • 3 tablespoons light muscovado sugar
  • salt, to taste
  • fresh ground black pepper, to taste

Method

  • Preheat your oven to 190C/375F/Gas 5.
  • Put your onions in an oven dish that will fit them neatly in one layer.
  • You might want to line the dish with baking paper, as the sauce will caramelise, which can make it quite a pain to clean.
  • Heat the oil in a frying pan and saute the celery over medium heat until soft, for about 5 minutes.
  • If you're not using any celery, just start with the next step, but shorten the frying time to two minutes.
  • Add the garlic and saute for a further five minutes.
  • Remove the pan from the heat and add all the other ingredients, apart from the onions and stir until the sugar has dissolved.
  • Season liberally with salt and pepper and pour the mixture over the onions.
  • Mix well until all the onions are coated evenly.
  • Place in your oven and roast for about one hour, stirring once halfway through.
  • You might want to check after 45 minutes, the onions are done, when they are soft and caramelised.
  • The time depends a bit on their size.
