Method

1. Heat a deep non-stick frying pan over a medium heat. Add the butter and when it sizzles, add the leek and bacon and fry for 6–8 minutes, until the leek is softened and caramelised and the bacon crispy.

2. Pour in the wine and allow to bubble for a couple of minutes before adding the mushrooms. Cook for 2–3 minutes to soften, then add 350ml/12fl oz beef stock and season well with salt and pepper. Reduce the heat to low and simmer for 25–30 minutes, adding a touch more stock if needed.

3. Stir in the crème fraîche, paprika and a knob of butter and simmer for a further 5 minutes.

4. Check the seasoning and serve garnished with chopped parsley.
