Sweet potato fish cakes with a delicious garlic and chilli sauce.
A very easy to make recipe for restaurant standard fish cakes. Using tinned salmon and crab along with a few kitchen essentials, this recipe is a real winner. The sauce made from butter, garlic, chilli, lemon, white wine, fish stock, parsley, tarragon and diced tomato completes the dish.
The two most important things are to make sure the sweet potato mash is as dry as possible and also to avoid the temptation to turn them too early in the pan – otherwise they will not hold together as you cook. Please don’t mistake the colouration for burning, it’s this crust that holds the cakes together.
This recipe makes 6-8 fishcakes
Ingredients and method
For the Fish Cakes:
750g Sweet potatoes – peel and thinly slice
250g shredded crab meat – 2 small tins drained of brine
200-225g red salmon – 1 small tin drained of brine
1/2 tsp sweet smoked paprika
1/2 tsp freshly ground black pepper
25-50g breadcrumbs – see notes below
2- 4 tbsp. oil to pan fry – I used Scottish rapeseed oil.
You require a food processor for this recipe
For the Sauce:
2 round tomatoes – diced
1/3 glass of dry white wine
3 cloves garlic – crush or finely chop
1 red chilli – deseed and finely chop
200ml fish stock
1 tbsp. fresh squeezed lemon juice
1/2 tsp dried tarragon
1/2 tsp dried parsley
Freshly ground black pepper – to taste
Method: Start by par boiling the sliced sweet potatoes – put them in a pan of cold water, heat through to the boil then simmer for 7-8 minutes. Drain them then put them back in the dry pan over a low heat for a few minutes (shaking the pan occasionally), then turn off hob and let the residual heat dry the potatoes. If they still seem wet leave them on the heat for a few more minutes. It is vital to dry the potatoes out as much as possible.
Once dried and cooled transfer the potatoes into a food processor. Add 25g breadcrumbs, 1/2 tsp black pepper, the crab and salmon and blitz until combined into a smooth paste. Check the consistency of the paste – you want it to be thick enough that patties can be formed in your hands without them immediately falling apart. If when you test the mixture it seems too wet add the rest of the breadcrumbs as they will absorb the excess moisture.
Start forming the fish cakes – you want them to be about 3cm thick and slightly wider than a standard coffee mug. Don’t make them much bigger or thicker than this as they may not hold together when cooked if they are too big or cook in the middle if they are too thick. See the picture at the top for an example of size. AS you form each one set aside on a plate ready to pan fry.
Before pan frying the fish cakes start to make the sauce as you want the sauce to reduce and intensify in flavour. Start by melting the butter in a small frying pan (a wide pan will reduce far quicker than a saucepan) then add the garlic and chilli then fry for 3-4 minutes stirring frequently. Next add the white wine and cook it off for a few minutes, then add the fish stock along with the dried herbs. Stir well and leave sauce simmering on a medium low heat for 10-15 minutes or until it has reduced by half. Turn off the heat as the sauce will be reheated when the fish cakes are ready – the tomatoes, pepper and lemon juice are added as the sauce
To pan fry the fish cakes – use a wide plat non stick frying pan, take care not to overload the pan as you need enough room to flip the fish cakes, cook in batches of max 4 if using a 30cm frying pan like me. Heat 2 tbsp. oil in the frying pan over a medium high heat. Add the fish cakes one at a time, giving them a final squeeze into shape just as you add them into the pan. They will need approx. 4 minutes on first side – the clue that they are ready is you should be able to see the crust forming on the edges and the cakes should easily slide on the pan. It is vital not to turn them too early as the cakes will either fall apart or loose shape. Once turned they should cook slightly quicker on the other side – approx. 3 minutes . Again the fish cakes will slide easily on the pan when the crust is formed and they are ready. Transfer to the plate ready to serve, or place on a baking tray and keep in a warm oven if you are making two batches.
To finish the sauce – heat the sauce through over a medium heat, once hot add 1 tbsp. freshly squeezed lemon juice and the diced tomatoes, stir through the sauce and continue to cook for 1-2 minutes. You want to warm the tomatoes through but not cook them, they bring a freshness and balance to the rich slightly acidic sauce. Add a little freshly ground black pepper to taste, then get ready to serve.
Place the cooked fish cakes on a serving plate and spoon some of the sauce over the fish cakes and onto the plate as shown in the pictures. Enjoy!
