Choose juicy red sun-ripened plump tomatoes for the best flavour.

Ingredients

• 1 red onion, peeled and finely diced
• 8 cloves garlic, peeled and chopped
• 6 tbsp virgin olive oil
• 1 tsp salt
• 1 tsp ground black pepper
• 1 tsp sugar
• 6-8 plum tomatoes, halved

Method

1. Heat the oil in a small saucepan and cook the onion and garlic over a low heat until softened.
2. Toss the onion mixture with the salt, pepper, sugar and tomatoes together.
3. Place the mixture into an oven-proof dish, making sure the tomatoes are cut side up.
4. Cook at 120ºC for 2½ hours until softened and smelling wonderfully fragrant. Keep in an airtight container in the fridge, but serve at room temperature.
