Step 1

Drain the canned fish and remove the bones. If you're using cooked fresh fish, make sure to de-bone the fish as well.

Step 2

Heat 2 tbsp of vegetable oil or coconut oil in a large non-stick pan over medium-high heat.

Step 3

Add the finely chopped onion and saute for a few minutes until they've softened. Add the garlic, ginger and saute for a further 30 seconds until softened.

Step 4

Add the curry powder, cayenne pepper, black pepper. Mix through the onions.

Step 5

Add the fish and mix with the onion-spice mix. Break the fish into smaller pieces and saute until the mix is dry, and it takes on the color of the spices - about 10 to 15 minutes. Do not let the mix burn (reduce the heat if necessary). Add the tomato ketchup and green chili peppers (serrano peppers) and mix through, and cook for a further 5 to 10 minutes.

Step 6

Season with salt if needed (remember you are using brined mackerel, so you may not need a lot of salt).

Step 7

Mash the potatoes (some smaller chunks are ok!), and add this to the fish mix. Mix well. Sprinkle the lime juice over the fish and potatoes and mix well. Season and add more lime juice and salt if necessary.

Step 8

Let the mix cool down.

Step 9

In a large non-stick pan, heat the oil over medium heat. When the oil is hot, add the breadcrumbs and stir to combine the breadcrumbs with the oil as evenly as possible.

Step 10

Stir frequently, until the breadcrumbs turn a golden brown in color and are evenly toasted. Make sure to not let the breadcrumbs burn.

Step 11

Immediately place the toasted breadcrumbs in a bowl and let it cool (uncovered).

Step 12

Preheat the oven to 350°F / 180°C. Line a baking sheet with parchment paper, and set aside.

Step 13

Break the eggs into a bowl and whisk gently to mix. Do not over beat and let it form too many bubbles. Optional - add a pinch of salt to the eggs and mix evenly.

Step 14

Place the toasted breadcrumbs on a plate.

Step 15

Portion the fish filling into 17 - 20 portions. Shape each portion into round or oval disc-like shapes.

Step 16

Evenly coat each cutlet with the eggs. Make sure there's no excess egg on the cutlets. You can use a fork to dip the cutlets in the eggs to make it easier.

Step 17

Next, place the egg coated fish cutlets in the toasted breadcrumbs and coat them evenly. Use your fingers to gently press the breadcrumbs into the cutlets to form a smooth crust, with no cracks.

Step 18

Repeat the egg wash and breadcrumb coating once more. This second coating is optional, but recommended for a crunchier crust.

Step 19

Place the coated cutlets on the lined baking tray, with about 1 - 2 cm of space between each.

Step 20

Bake in preheated oven for about 5 - 7 minutes. Turn each cutlet over and bake for a further 5 - 7 minutes.

Step 21

Remove the cutlets from the oven and let them cool slightly. Serve while very warm with tomato ketchup or tomato relish.

Step 22

You can reheat the cutlets, by placing them in the warm oven for a few minutes.
