Portuguese fish stew (Caldeirada de peixe)

Heat a drizzle of oil in a large, deep-sided frying pan, and fry the onion and pepper on a medium heat until softened but not browned. Finely chop the coriander stalks (keep the leaves for later), and add to the pan with the chilli and chopped garlic. Fry for another few minutes. Add the wine, saffron and bay leaf and let it simmer until reduced by half.

Add the potatoes, tomatoes, and 300ml water and bring to a gentle boil. Break up the tomatoes with a spoon on the side of the pan and simmer for 20-25 minutes until the potatoes are just tender, and the tomatoes have broken down.
