Roast Potato, Smoked Fish and Asparagus Salad with Preserved Lemon Dressing

Preheat the oven to 200°C. 

Toss potato slices in the ghee or oil and place in a single layer in a large ovenproof dish. Roast for 35–40 minutes until tender and golden brown.

Combine all the dressing ingredients and use a hand blender or a mini food processor to blitz until as smooth as possible. Season generously. The dressing should be on the salty side and the saltiness of the preserved lemons can vary between brands. Adjust accordingly.

Bring a large pot of water to a boil. Blanch the asparagus for 1 minute before plunging into icy water. This helps retain the bright green colour. Drain well.

Lay the hot potato slices out on a plate. Scatter over the asparagus. Break the smoked fish into large chunks and place on top. Add generous dollops of dressing and garnish with dill and a grind of black pepper. Serve immediately.
