Smashed celeriac
This seasonal side dish goes beautifully with a roast, alongside sausages instead of mash or with baked meaty fish like pollack or hake
Heat 1 tsp of the olive oil with the butter in a large non-stick frying pan until it just starts to sizzle. Add the fish, skin-side down, and fry for 10-15 mins – basting often until the skin is crisp and the flesh has cooked through – then turn over for a min. Remove and keep warm.
Add the remaining oil to the pan and tip in the bacon lardons and croutons. Fry for about 10 mins until crisp. Meanwhile, toast the flaked almonds in a dry pan over a medium heat. In a small bowl, whisk together the oil and vinegar for the dressing with some seasoning, then set aside. Toss the watercress, beetroot, lardons, croutons, almonds and dressing together in a large bowl. Sit a trout fillet on each plate and serve with the salad on the side.
