How to Make Potato and Haddock Cakes
Step 1: Cook the Potatoes
Peel the potatoes and cut them into evenly sized chunks. Place in a pot of salted water and bring to a boil. Cook for 15–20 minutes, or until the potatoes are very tender.
Drain well and allow excess steam to evaporate. Mash with butter and a little milk until smooth but not overly soft. Set aside to cool.
Step 2: Cook the Haddock
Place the haddock in a shallow pan and cover with water or milk. Bring to a gentle simmer and cook for 6–8 minutes, until the fish flakes easily.
Remove from the liquid and allow to cool slightly. Flake the haddock into small pieces, carefully removing any bones or skin.
Step 3: Prepare the Mixture
In a large bowl, combine the mashed potatoes and flaked haddock. Add the chopped onion or shallot, parsley, and beaten egg. Season lightly with salt and pepper.
Mix gently until just combined. Avoid overmixing, as this can make the cakes dense. If the mixture feels too soft, refrigerate for 20–30 minutes to firm up.
Step 4: Shape the Cakes
Divide the mixture into equal portions and shape into round or oval patties, about 2–3 cm thick.
Lightly coat each cake in flour or breadcrumbs, shaking off any excess. This helps create a crisp exterior during cooking.
Step 5: Fry Until Golden
Heat a thin layer of oil in a large frying pan over medium heat. Add the cakes in batches, making sure not to overcrowd the pan.
Cook for 3–4 minutes per side, or until golden brown and heated through. Transfer to a plate lined with paper towels to drain excess oil.
Tips for Perfect Fish Cakes
-
Use floury potatoes for a light, fluffy texture
-
Allow potatoes and fish to cool before mixing
-
Season gently—especially if using smoked haddock
-
Chill the mixture if cakes are too soft to shape
-
Turn cakes carefully to prevent breaking
