Mackerel Rolls with Watercress Ketchup and Flatbreads

From Britain The Cookbook by Phil Vickery, he writes "Not only is this fresh mackerel recipe very quick and easy, but it makes a great accompaniment to all sorts of dips and sauces". The watercress sauce is a great accompaniment to any fish.

Serves 4

    4 medium mackerel fillets, boned but skins left on
    Salt and freshly ground black pepper
    Olive oil for brushing
    2 tbsp chopped basil
    2 tbsp pitted black olive rings

For the Ketchup

    3 tbsp olive oil
    2 small onions, peeled and very finely chopped
    1 garlic clove, peeled and very finely chopped
    300ml (10fl oz) water
    ½ vegetable stock cube
    2 tbsp light soy sauce
    2 tbsp runny honey
    1 level tbsp cornflour, slaked in 2 tbsp cold water
    255g (9oz) watercress
    3 heaped tbsp frozen peas
    3 tbsp mayonnaise
    A squeeze of lemon juice

For the Breads

    225g (8oz) self-raising flour
    2 tbsp good-quality olive oil
    4 tbsp chopped mint
    4 tbsp natural yoghurt

Method

To start the ketchup, heat the olive oil in a large saucepan, then add the onion and garlic and cook for 5 minutes to soften.

Next add the water, stock cube, soy and honey, bring to the boil and cook for 5 minutes. Then thicken with the cornflour, stirring it in well. Add 85g (3oz) of the watercress and all the peas and cook for a further 1-2 minutes until the watercress is softened. Pour into a large tray or bowl over ice to cook as quickly as possible. This will keep the deep green colour. Once cooled, spoon the cooled mixture into a liquidiser, add the remaining watercress and blitz for a good 3-4 minutes or until very smooth. Whisk in the mayonnaise and lemon juice and chill.

Meanwhile, for the breads, preheat a griddle or frying pan. Mix the self-raising flour, some salt, the oil, mint and yoghurt together to form a loose dough (using a little water if needed). Roll out to about 1cm (½in), or possibly slightly thinner; do not overwork. Pop the breads straight on to the hot dry griddle or frying pan and cook on each side for about 4-5 minutes, or until slightly puffy and blistered. Leave to cool and cut into wedges or strips.

Preheat the oven to 200C/400F/gas mark 6 or the grill to a moderate or high heat. Lay out the mackerel fillets on your work surface, season well with salt and pepper and brush with olive oil. Sprinkle on a little chopped basil and a few rings of olive. Roll up and secure with a wooden cocktail stick. Brush with more oil. Heat a non-stick heatproof and ovenproof pan and add a touch of oil. Place the rolls in the pan and cook for 2-3 minutes. Place in the oven or under the grill for 10 minutes. Do not overcook. Serve the rolls with the breads and watercress ketchup.

RECIPE TIPS

Phil suggests if you roll out the dough even thinner, it makes a good base for canapés or finger food.
