Instructions
If using whole coriander and cardamom, grind them finely. Remove the black seeds from the cardamom pod and discard the pod. It's easiest to grind the seeds in a mortar and pestle with a pinch of salt to provide some friction. Leave the cumin seeds whole.
Heat a pan over a medium heat and add the olive oil. Fry the cumin seeds for a couple of minutes, making sure that they don't burn. (If using ground cumin omit this stage and add the cumin along with the other spices.)
Add the chopped onion, garlic, seasoning and remaining spices to the pan. Fry for 7-8 minutes until the onion softens and starts to turn brown.
Add the diced marrow, along with a couple of tablespoons of water. Mix, and cover the pan. Cook over a low heat for 20 minutes. Check frequently to ensure the curry doesn't stick or burn on the bottom of the pan. Add a splash more water if necessary. When cooked the marrow should be soft to the point of a knife.
Notes
If you prefer, replace the spices with 2 tablespoons of ready blended mild curry powder.
For a hotter curry, add half a teaspoon of chilli powder (or to taste).
You could also use courgettes or squash in place of marrow.
To serve as a vegetarian main course, add some extra protein such as tinned chickpeas, cooked lentils or a handful of almonds or cashews.
For a creamy marrow curry, add a can of coconut milk to the pan for the last 10 minutes of cooking time.
