- 500 g floury potatoes, peeled and cut into 4cm chunks
- 3 Tbsp. vegetable oil
- 2 tsp. coriander seeds, lightly crushed with a pestle and mortar
- 1 tsp. black mustard seeds
- 1 onion, roughly chopped
- 1 red chilli, deseeded and finely chopped
- 2 garlic cloves, crushed
- 1 tsp. turmeric
- 250 g spinach
- 500 g skinless cod fillets, cut into 2cm chunks
- 2 Tbsp. mango chutney, we used Geeta’s
- Step 1Put the potatoes into a large pan, cover with cold water and bring to the boil. Reduce heat and simmer for 10-13min, until tender. Drain thoroughly and leave to steam dry for 5min.
- Step 2Return potatoes to the pan and mash with plenty of seasoning, until smooth. Set aside to cool.
- Step 3Meanwhile, heat 1tbsp oil in a separate pan over medium heat and fry the crushed coriander and mustard seeds for 2min, until fragrant. Add the onion and cook for 10min, stirring occasionally, until softened. Stir in the chilli, garlic and turmeric and cook for 1min.
- Step 4Add the spinach, stir to wilt then cook for 2min more, or until most of the moisture has evaporated. Set aside to cool.
- Step 5In a large bowl, mix the mashed potatoes, cooled spinach mixture, cod, mango chutney and plenty of seasoning. Shape into 8 patties, arrange on a baking tray lined with baking parchment and chill for 10min.
- Step 6Heat 1tbsp oil in in a large, non-stick frying pan over medium-high heat. Fry 4 fishcakes for 3-4min per side, until piping hot and golden. Lift on to a baking tray lined with kitchen paper to drain briefly. Repeat frying and draining with remaining fishcakes, adding remaining 1tbsp oil to the pan first. Serve with a crisp green salad.
Freeze Ahead:
Prepare to end of step 5. Stack patties into a freezer-safe container, separating each layer with baking parchment. Cover and freeze for up to 1 month. To serve, defrost in the fridge before completing recipe.
