We've kept the spicing quite mild, making it suitable for the whole family, but you can increase the quantity of curry powder or fresh chilli if you like it spicy. The poppadum topping is optional, but it adds a crunchy texture.
2 tbsp rapeseed oil, plus extra for drizzling
2 onions, chopped
500g lamb mince
thumb-sized piece ginger, peeled and grated
3 garlic cloves, crushed
1⁄2 tsp ground cinnamon
1 tsp turmeric
2 tbsp mild or medium curry powder
1 tbsp tomato purée
1 lamb or beef stock cube pinch sugar
2 large sweet potatoes, peeled and cut into chunks
4 large potatoes, peeled and cut into chunks 1⁄2 the size of the sweet potato chunks
50g mature cheddar, grated
250g frozen peas
2 poppadums (optional)
1 green chilli, thinly sliced (optional)
Heat the oil in a large pan and cook the onions until soft and starting to brown, about 8-10 mins. Push to one side of the pan and add the lamb. Leave it alone until the underside is browning, then break it down with the back of a spoon. Leave to brown for a few mins more, then stir in the ginger, garlic, spices and tomato purée. Stir for a few mins until the mixture is sticky and aromatic. Add 600ml water, the stock cube and sugar. Bring to a simmer, then lower the heat and cook for 45 mins, stirring occasionally to prevent it from sticking. The sauce should be thick, but if it reduces too quickly, add a splash of water or cover with a lid.
Put the sweet potatoes and potatoes in a pan and cover with cold water. Bring to the boil, cover with a lid and simmer for 15 mins until tender. Drain and leave to steam dry for 10 mins.
Mash the potatoes with the cheese and some seasoning. Tip the mince into a baking dish about 20 x 35cm and 10cm deep. Stir in the peas. Cover with the mash, making dips and peaks with the back of your spoon, or pipe the mash on for a neater nish. Crush the poppadums in your hands and scatter over the mash, then drizzle over a little oil. You can now chill for up to two days or freeze for two months. If cooking straightaway, heat oven to 180C/160C fan/gas 4.
Bake for 45 mins until golden and bubbling around the edges. Leave to cool for 5 mins before serving, with the green chilli scattered over, if you like.
