Slice tough ends of the marrow and discard, then cut the marrow into half, lengthwise and then chop into half moon shapes. Set aside.
Place a large pan (I use , which is 30cm / 12in) on the stove on medium-high heat and add 3 tablespoons olive oil, shallots, pinch sea salt, turmeric powder, cumin powder, coriander powder, red chili powder and sliced marrow. The marrow will become soft after 7-10 minutes. You don’t want the marrow to completely disintegrate, so don’t let it overcook.
Turn the heat to high, add the minced garlic and let the marrow turn golden – it should look blistered and slightly charred. Make sure to flip the marrow slices so that both sides are bronzed/charred. If you want, you can add more olive oil if the marrow is sticking to the pan. Set aside and allow to cool.
Place a medium-sized pan on medium-high heat and add the remaining 3tbsp olive oil and sliced fennel. *Saute gently for 10-15 minutes till wilted and bronze around the edges.
Set fennel aside and allow to cool.
Using a slotted spoon, remove the marrow from the pan and transfer to a chopping board (you don’t want to use all the excess olive oil). With kitchen shears or a knife, finely chop the marrow.
Do the same with the fennel. Reserve two tablespoons of the fennel to add as a garnish.
Gently combine chopped marrow and fennel into yoghurt. Adjust taste for salt.
Adorn with the reserved fennel. Drizzle with your favourite olive oil, dust with pul biber (or paprika) and adorn with fennel fronds.
Enjoy with lots of warm bread.
