Step 1

You can make this on the day, if you prefer. Preheat the oven to 180C fan-forced (200C conventional). Scrub the pumpkin (there’s no need to peel it), carefully halve it lengthways and deseed, then chop into 2cm chunks. Place in a roasting tray, toss with 1 tablespoon of olive oil and a pinch of sea salt and black pepper, then roast for 1 hour, or until soft and caramelised.

Step 2

Meanwhile, peel and roughly chop the onion, peel the garlic and ginger, and dry fry in a non-stick frying pan on a medium-high heat with the coriander and fenugreek seeds and the curry powder, stirring until lightly charred all over. Add the tomatoes and pineapple rings (reserving the juice), and cook for 10 minutes to soften and char, stirring regularly. Tip it all into a blender, add the coconut milk and blitz until very smooth. Return to the pan, tip in the chickpeas, juice and all, and simmer gently until the sauce is thickened. Stir in the roasted pumpkin, then season the curry to perfection, tasting and tweaking, and loosening with the reserved pineapple juice. Cool, cover and refrigerate overnight.

Preheat the oven to 150C fan-forced (170C conventional). Place the covered pan of curry in the oven until hot through – about 1 hour. Nice with picked coriander leaves.
