Put ½ of the ginger, 2 quartered onions, 300ml water and 4 garlic
cloves in a food processor. Blend it together to a purée.
Tip into a deep frying pan, cover with a lid and let it simmer for
about 15 mins.
Remove the lid and cook for another 5 mins more, stirring
occasionally - this will make the liquid dissapear.
Add 2 tablesoons of rapeseed oil to the pan with the rest of the
ginger. Fry and stir, for 3-5 mins until it starts to get colour.
Add 1 cinnamon stick, 1 tablespoon ground coriander, 1 teaspoon
ground cumin, 1 teaspoon ground turmeric and ½ teaspoon fennel
seeds, then add the 750g lamb. Stir-fry until the lamb changes
colour.
Add in 400g can chopped tomatoes with a can of water and 1 deseeded
and sliced red or green chilli, cover and let it simmer for
approximately 1 hour.
Stir in the finely chopped stalks from a small bunch coriander and
cook for a another 30 mins until the lamb is tender. Add a little of
water if necessary to loosen the consistency as it cooks.
Stir in the chopped coriander leaves and serve it with basmati rice
and mango chutney.
