Method
- Heat the oil in a large pan, then fry the shallots for five minutes.
- Add the peppers, chilli flakes, bay leaf and thyme, season and cook, stirring occasionally, for 30 minutes until soft.
- Add the sherry vinegar, cook for a few more minutes, then take off the heat and leave to cool.
To make the pastry
- Tip the flour and salt into a bowl, then rub in the cold diced butter with your fingertips until the mix resembles breadcrumbs.
- Mix half the beaten egg with two tablespoons of cold water and the vinegar, add to the flour bowl and mix in quickly.
- Bind dough together with your hands, knead very briefly on a floured surface until smooth.
- Wrap and chill for at least 30 minutes.
- Heat the oven to 200C (180C fan)/390F/gas 6 and line a baking sheet with greaseproof paper.
- Divide the chilled dough into six equal-sized pieces and roll each one into a ball.
- Roll out each ball into a large disc, then use a pastry cutter or small plate to cut out a 16cm circle.
- Transfer to the lined baking sheet and brush all over with the remaining beaten egg.
- Bake for 20–25 minutes, until golden brown, then serve warm or at room temperature.
