Preparation sauce
- Chop the onion and garlic.
- Cut the center of the celery into rings.
Heat the onions and garlic in a hot pan with a little bit of butter. As soon as the garlic starts to brown, add the celery. Turn this on and then add the tops of the fennel and the leek greens. - Deglaze with white wine. Add 1.5 liters of water and let it simmer for an hour until you have a nice vegetable stock.
Strain the stock as soon as it is tasty.
- Then make a roux. To do this, melt the butter in a saucepan. Once the butter has melted, add the flour and stir well. The roux is ready when it starts to stick to the bottom of the pan.
- Add the stock in parts to the roux with a whisk.
- Season the sauce with the soy sauce and a little pepper. Put the sauce on low heat.
- Make a mixture of the egg and cream.
- Add the egg mixture to the sauce. Stir well immediately. If the sauce is a little too thick, thin it out with a little cream or water. Don't let the sauce boil!
Preparation potatoes
- Cut the leek into rings and keep the green.
- Cut the tops of the fennel and cut the leaves into thin strips. Keep the tops of the fennel with the leek green.
- Cut the potatoes into wedges and boil them for 5-8 minutes.
- Drain the potatoes and let them steam out.
- Heat some butter in the medium-sized pan and add the pre-cooked potatoes.
- Add the leek rings and sauté them. Continue the steps by adding the fennel, salt, pepper and a splash of white wine.
- Place the potato mixture over low heat, turning occasionally.
Preparation fish
- Take a frying pan and put a knob of butter in it.
- Place the fish with the skin in the bubbly butter. Turn the fish when the body is golden brown.
- Add another knob of butter and spoon it over the fish from time to time. Once the fish is almost cooked, add a dash of soy sauce and spoon this over the fish as well.
- Remove the fish from the pan and let it rest for a while.
- Place the cockles in the used pan of the fish, which still has all the flavor and butter in it. Stir well and add a splash of white wine to open the clams.
Plating
Spoon a few heaped spoonfuls of potato mixture into a deep plate. Then place the fish on top. Add a generous amount of sauce to the plate. Then put some cockles on the plate and sprinkle some chopped parsley over the dish.
