Beware: The roast needs to be cooked in the oven for more than 3 hours, so plan accordingly. The result will be quite something, though. Yes, it’s very fatty meat, but that’s what makes this so delicious. This dish is impossible to ruin; if you leave it in the oven for 30 minutes too long it won’t matter. Serve with something fresh-zesty. I like the horseradish mustard (see recipe below), for example. Such a substantial roulade serves a crowd, and whatever you have left over (if you manage to not finish all of it) will still be delicious the day after.
