You end up with a piece of meat that's practically raw in the middle and crusty on the outside, so you have to make sure you're using a really good piece of meat to start with.
The other great thing about this dish is the sauce - a mayo made with lots of fresh mint and mustard. Wouldn't have thought of mint and beef, but this works a treat. Served with new pots and a leafy salad. And to finish? What could be better than a traditional english trifle, made with fresh cherries from the village and whatever else we could find!
