A roast leg of lamb is an ideal St Patrick’s Day dinner, but you don’t just have to keep it for special days. It is one of those meals that is always good and, with quality assured lamb now available all year, you can enjoy it again and again. It is a perfect Sunday lunch and very easy to prepare.

If you haven’t cooked boulangère potatoes before, they are well worth trying. You will go back to them again and again, and having been cooked in stock, herbs and the lamb juices, they taste fabulous. I like this roast with the wilted spinach – it is full of iron.
