Step by step

1. Cut the tempeh into strips 1cm wide and 4cm long, then pat dry with kitchen paper. Toss with the cornflour and season.
2. Heat the vegetable oil in a pan and cook the tempeh, cumin seeds and mustard seeds over a medium-high heat for 3-4 mins or until golden and crisp. Remove with a slotted spoon and set aside.
3. Put the ginger, garlic, chilli and half the coriander in a mini food processor with 2 tbsp of water, and pulse until finely chopped but not completely smooth. Add to the tempeh pan and cook for 1 min until fragrant. Stir in the coconut milk and turmeric, then fill the coconut can half with water and add to the pan. Season.
4. Bring to the boil then turn down to a simmer, add the tempeh and veg, and cook for 10 mins until the veg is tender, stirring occasionally. Squeeze in one half of the lime, then cut the other half into wedges.
5. Finely chop the remaining coriander and stir through the cooked rice. Serve with the curry and lime wedges.
