This is the bargain of the week - a rolled breast of lamb from Asda, already cheap, but reduced to £1. I have cooked this lots of times, and it's been tasty, crispy but as tough as hell. This time I read the intructions in a recipe book instead of guessing and rushing, and it said SLOW cooking. So I put it on at 100, went to work for four hours and came back to the most delicious and tender piece of meat ever. Turned it up for twenty minutes to crisp up and WOW, what flavour! It's not for everyone as it's very fatty, but with rosemary, broad beans and the first new potatoes out of the garden it was as tasty as anything I have had lately. Next time I will unroll it, put some stuffing in and serve it to my best friends.
