4. Heat the oil in a saucepan and add the garlic and onions. Cover and cook for 10 minutes, until the onions have softened. Mix with the celeriac and potatoes

5. Pour over the stock and sprinkle with the chopped parsley. Scatter the breadcrumbs over the gratin.

6. Cover with foil and bake for 40 minutes, until the vegetables are tender and the breadcrumbs coloured.

7. For the fish; dust the fish fillets in seasoned flour mixed with the ground fennel seeds. Heat the butter and oil in a frying pan and cook the fish for about 2-3 minutes on each side. Serve with a pat of chilled lemon butter on top, accompanied with the gratin and a wedge of lemon on the side. Any left over butter can be stored in the freezer.
