Patatas bravas

1. Heat 1 tsp of oil in a small pan and add half the garlic and chilli. Cook gently for a minute, then add the tomatoes, tomato purée and a teacupful of water. Season with salt and pepper and simmer gently until thick. It should be spooning rather than pouring consistency.

2. Heat the rest of the oil in a large frying pan and add the potatoes. Cook over a medium low heat for half an hour or more, turning occasionally until deep golden brown all over. Don't be tempted to speed this process up. They need to be fried slowly to get the right delectable thick crust.

3. At the end of cooking combine the potatoes with the tomato sauce.
