The leek one. Lighter and brighter than the long-simmered curries — the leeks melt down into the sauce in five minutes and lemon zest at the end lifts the whole thing.
why it works
Melted leeks and chickpeas thicken the stock naturally, so there's no cream, no coconut milk and no flour anywhere in it. The lemon juice and zest at the end aren't decorative — acid is what stops earthy, bean-heavy food tasting flat and heavy.
Mix the curry powder, garam masala, turmeric, cumin, salt and pepper together in a small pot before the hob goes on.
Deep pan on medium-high with a light spray of olive oil. Diced chicken in with the garlic and ginger, stir-frying for 2–3 minutes until it colours.
Heat down to medium, then in with the onion and sliced leeks. Cook them down with the chicken for 4–5 minutes. The leeks melt into a sweet, rustic texture that's the whole character of this curry.
Tip the entire spice blend over and stir vigorously for 60 seconds so the dry heat toasts it onto the meat and veg.
Pour in the stock, add the chickpeas, and simmer gently with the lid on, on low heat, for 10–12 minutes.
Lid off. Stir in the lemon zest and juice — this is what wakes up the earthy chickpeas — then the mountain of spinach, stirred gently for 60 seconds until it wilts in.
