Directions

1. Bring a large pan of salted water to the boil, then tip in 1 1/4 kg trimmed Brussels sprouts. Once back to the boil, cook for 5 mins. Drain, run under the cold tap until cold, then drain again.
2. Heat a large frying pan, add 6 rashers smoked streaky bacon, cut into bite-sized pieces, and gently fry for 10 mins until crisp and golden.
3. Tip out of the pan, leaving the fat behind, then add 200g chestnuts and fry over a high heat for about 5 mins until tinged. Tip out of the pan.
4. Add the Brussels sprouts to the pan with a splash of water, then cover and finish cooking over a medium heat for about 5 mins, stirring now and again, until just tender.
5. Uncover, turn up the heat, then add most of the 50g butter and saute the sprouts for 2 mins more.
6. Tip in the bacon and chestnuts, season generously with salt and pepper, then serve with the last knob of butter on top.
