Step 1

Toss the lamb in the flour with a little salt and plenty of freshly ground black pepper. Heat the oil in a heavy-based pan, add the onion and fry for 5 mins until softened. Add the lamb and stir well until tinged brown.

Step 2

Stir in the stock, 2 tablespoons of the dill and the bay leaf. Bring to the boil, then simmer for 30 mins.

Step 3

Add the potatoes and lemon juice and cook for a further 30 mins until the potatoes are tender. Serve in soup plates or individual dishes with a spoonful of crème fraîche and a scattering of lemon zest and dill on each serving. Some crusty bread on the side will be useful for mopping up all the juices.
