Firstly prepare the vegetables: Cube the pumpkin into 2/3cm pieces (you can use butternut squash if you can’t find a pumpkin), slice your shallots, cut your plum tomatoes into half, chop your ginger into small pieces and crush your garlic. Lastly, chop your chillies into thin pieces. NB: If you prefer your curry not too hot, then deseed chillies first.
