For the mash:
- 1 lb floury potatoes, peeled and cubed, such as Russet
- 1 medium cauliflower, cut into florets
- 2 teaspoons grainy Dijon mustard
- 2 tablespoons brown butter
- Salt
For the fish:
- 4 sheets of parchment paper
- 4 white fish fillets
- 2 teaspoons olive oil, divided
- Salt & pepper to taste
- 1 lemon, thinly sliced
- 2 cloves garlic, thinly sliced
- 4-8 leaves sage
- 3.5 oz sugar snap peas, julienned
- 2 medium carrots, julienned
INSTRUCTIONS
To make the brown butter:
- Put the stick of butter in a small pot or pan over medium-high heat. Heat until it starts to bubble, immediately reduce to the smallest setting on your stove and cook until you notice a nutty smell.
- Remove any foam on the surface with a spoon, then strain through a piece of cloth or some strong kitchen paper into a clean jar. Store in the fridge for up to three months.
To make the mash:
- Cook the potatoes and cauliflower in salted water until tender.
- Drain and mash with a potato masher. Add mustard and brown butter and mix well.
To make the fish:
- Preheat the oven to 425°F.
- Spread one sheet of parchment paper on an even surface. Lightly brush the middle with a bit of olive oil. Put one fish fillet in the middle of the paper. Season with salt and pepper and top with a drizzle of olive oil, garlic, lemon and sage leaves. Put 1/4 of the vegetables on either side of the fish. Wrap the parchment paper around the fish into a parcel. Proceed in the same way with the other three fillets.
- Bake on a baking tray for 12-15 minutes. Serve immediately and still wrapped in the paper.
