Hake, Celeriac Puree, Mustard Leek Sauce

Hake, Celeriac Puree, Mustard Leek Sauce
Hake, Celeriac Puree, Mustard Leek Sauce

Something a little different to make for dinner tonight on this damp and rainy day; transform hake fillets and a couple of leeks and celeriac you may have in the fridge into this comforting creamy fish dish.

Made with a splash of white wine, crème fraîche, Dijon mustard and in less than half an hour, this is the perfect fish dish that is low in carbohydrates. I know you’ll enjoy the delicate flavour of a hake with the sweet leeks and creamy celeriac puree.

This is very much one of those recipes that came about from things that were in the fridge. For me, celeriac is a staple root vegetable in the winter months. I love to make a hearty soup or a gratin from it. I always buy leeks too. So good as a side at Sunday lunch, and the green part is great to add to stocks.

Pickled Mustard seeds

Also known as ‘mustard caviar’ due to the similar popping texture, Pickled Mustard Seeds are not essential in this dish, but they do add a little piquancy. They are perfect for cutting through anything rich or fatty. In this case the creamy mustard sauce. Try them stirred through scrambled eggs…so good! Or you could add them to the Lemon Butter Sauce with Smoked Haddock Fishcakes.

Pickled Mustard Seeds

You could easily substitute with other fish. I suggest salmon, haddock or cod. The celeriac purée can be made in advance, then all you have to do is sauté the fish, cook the leeks and make the sauce. I haven’t included the time for making of the Pickled Mustard Seeds in this recipe. In all honesty, it takes minutes and can be made a few days prior to making this dish and stored in the fridge. If the pickling liquor has absorbed into the seeds, just add a little more vinegar and water.

Ingredients

Pickled Mustard Seeds

  • 50 g mustard seeds
  • 140 ml white wine vinegar
  • 40 ml water
  • 50 g sugar
  • 3 coriander seeds
  • 1 bay leaf
  • 3 peppercorns
  • a good pinch fine sea salt
  • 2 pieces Hake fillet approx 130g each

Celeriac Puree

  • 500 g celeriac peeled & cut into chunks
  • 1 garlic clove
  • 15 g butter
  • 2 tbls whole milk
  • 2 Tbls double cream or creme fraiche
  • 2 small leeks sliced

Sauce

  • 80 ml fish stock
  • 1 shallot finely chopped
  • knob butter
  • 1 tsp Dijon mustard
  • 60 g double cream or crème fraîche I prefer crème fraîche
  • 80 ml dry white wine
  • 1 tbls chopped parsley

Instructions

Pickled Mustard Seeds

  • Pop all of the of ingredients in a small saucepan and bring to a slow boil. Stir several times, making sure the sugar has dissolved. Reduce the heat and simmer for about 5-8 minutes. Remove from the heat and allow to cool to room temperature. Transfer to a sterilised jar and store in the fridge.
  • Begin with melting a knob of butter in a saucepan and then add the garlic. Follow with the celeriac and 50ml water a large pinch of salt. Cut a round piece of baking paper the same size as the pan and use to cover the celeriac (cartouch). Cook gently for 15-20 minutes, stirring regularly, until the celeriac is very soft and starting to collapse, you may need to add a splash of water. Blitz in a high speed blender, then pour back into the saucepan. Simmer to drive off any excess water that may still remain in the puree. Season if needed and add the milk and creme fraiche. Set aside.
  • Now to make the sauce. Gently saute the shallot in a little butter for a few minutes to soften before adding the white wine. Let it bubble gently for a minute or so and then pour in the fish stock. Now add the Dijon mustard and creme fraiche. Whisk it all together, season and then take off the heat and set aside while you sauté the hake. Brush the fillets first with olive oil, season. Sauté in a medium-hot frying pan for 3-4 minutes each side, depending on the thickness.
  • In the meantime, gently simmer the leeks in water for 2-3 minutes or just cooked through. Gently heat the mustard sauce through, add the parsley.
  • Spoon the celeriac puree onto the plate, top with the fish and spoon the sauce and leeks onto each plate. Scatter with pickled mustard seeds. Serve immediately.

Notes

*This recipe can be doubled to serve 4 quite easily.

Raspberry & Hibiscus Birthday Cake That pink is Raspberry & Hibiscus Birthday Cake 

That pink is freeze-dried raspberry powder through the Swiss meringue buttercream - for flavour of course, but it also turns the whole lot this gorgeous natural pink. Finished with fresh edible flowers. You can catch the assembly over on stories if you fancy seeing how it all came together.

In other news, we’ve been making the most of these cooler temperatures for eating outside. Pizza, baked fish, spatchcock chicken, on the Big Green Egg. I love eating al fresco.
We’re off to the Cornish coast soon too, and very much looking forward to the sea air, proper coastal walks and even better fresh fish.

Crustless Quiche I’ve filled this with griddled c Crustless Quiche

I’ve filled this with griddled courgette and oven-roasted tomatoes, though it really is one of those recipes that works with whatever vegetables you have in the fridge.

The cottage cheese stands out here - it gives the whole thing a lovely creamy, slightly sour depth that you don’t expect. Along with 6 eggs, a good mature hard cheese and a couple of tablespoons of crème fraîche, that’s genuinely all you need. Bake in a 20cm/8inch lined tin.

180°C for 35 minutes. Equally good warm or at room temperature, which makes it very useful for this time of year.

It’s been a while – I’ve been off grid since Easte It’s been a while - I’ve been off grid since Easter, caught up in family commitments that took over life for a bit. I hadn’t planned to be away quite so long, but sometimes things just unfold and life takes you in a direction you don’t expect.

I can’t quite believe we’re already at midsummer. The weeks seem to have slipped by at an alarming rate this year, and here we are with the longest days almost behind us. Time moves far too quickly.

Anyway, I’m back, and there’s plenty to share. Happy midsummer! 🌿

Happy Easter to everyone celebrating. The Swedish Happy Easter to everyone celebrating.

The Swedish half of me tends to take over in the kitchen at this time of year. Here are just a few of the things I’ve been cooking and baking this weekend — smörgåstårta using home-baked sourdough with savoury fillings. 

An appetiser of whipped cream cheese with fresh grated horseradish and lemon zest, topped with smoked salmon, pickled red onion and cucumber.

And buns filled with forced rhubarb and custard, which I think is a pretty hard combination to beat.

Our magnolia tree is stunning this year too — one of my favourite signs that spring is finally here. Hope everyone’s having a good one 🌷​​​​​​​​​​​​​​​​

Now that we’re in wild garlic season this is a spr Now that we’re in wild garlic season this is a spring gratin worth making. You can swap half the potato for celeriac — it brings an earthiness that balances the richness of the cream and the smokiness of the salmon beautifully.

Wild Garlic, Potato & Hot Smoked Salmon Gratin — serves 4

250g hot smoked salmon, flaked
900g King Edward potatoes, peeled & thinly sliced (or swap with 450g for celeriac)
2 leeks, white part only, sliced
2 cloves wet garlic, sliced (or 1 regular clove)
80g wild garlic, roughly chopped
180ml whole milk
245ml whipping or double cream, or crème fraîche
35g mature hard cheese, grated
Butter and olive oil, for sautéing

Preheat the oven to 180°C fan. Sauté the leeks in a little butter and olive oil until soft, then add the wild garlic and wet garlic and cook until the leaves have wilted. Gently heat the milk and cream with 25g of the cheese, whisking until smooth. 

Layer the potatoes, leek mixture and flaked salmon in a baking dish, seasoning lightly between each layer, and finish with a top layer of potato and a few wild garlic leaves. Pour over the cream sauce and scatter with the remaining cheese. 

Cover with foil and bake for 40 mins, then uncover and bake and bake for a further 25-30 mins or until cooked through. Serve with a crisp green salad.

I’ve been a little quiet on here lately. Behind t I’ve been a little quiet on here lately.

Behind the scenes it’s been a full season — family needing me, and a steady stream of celebration cakes keeping the kitchen going. The two together don’t leave much space for anything else.

But March has a way of making you look up. The light is back, British Summer Time is almost here, and nature is doing something rather extraordinary this year — the bluebells are out almost a month early. Beautiful and a little baffling. And the wild garlic is here too, which always feels like a quiet celebration of its own.

Glad to be back. Tell me — what have you been up to?
