Indian potato pie

Method

• step 1

  Put the potatoes in a large saucepan of cold, salted water, then bring to the boil. Turn down and simmer for 5 mins, add the sweet potatoes and continue to cook for 8 mins until just tender. Drain really

• step 2

  Fry the onion in the oil until soft, add the cumin seeds for 1 min, then stir in the garlic, chilli and ginger with the remaining spices. Cook for a further 2-3 mins, then turn off the heat and stir into the potatoes with the peas, lemon juice and coriander.

• step 3

  Heat oven to 190C/170C fan/gas 5. Halve the filo sheets, and use two-thirds of them, overlapping, to line a 22cm loose-bottomed cake tin with a little overhang. As you lay in each sheet, brush with melted butter and keep the rest covered with a clean tea towel. Spoon in filling and press down lightly. Cover with remaining filo, then fold up overhanging sides and scrunch up pastry near the edges.

• step 4

  Poke several slits in the top of the pastry and brush with more butter. Sprinkle with the poppy seeds. Bake for 40-45 mins until golden brown. Serve either hot or at room temperature with lemon wedges.
