Tomatoes take on an intense, deep flavour after roasting and a versatile ingredient for lots of other recipes. Here, we add garlic, balsamic vinegar and thyme
Heat the oven to 160C/140C fan/gas 3. Put the tomatoes on a baking sheet with the garlic and thyme, drizzle over the balsamic vinegar and olive oil. Add some seasoning and roast for 1 hr. Remove and set aside to cool.
