Difficult to say - love them all. DH would have roast every day of the week if he could. He often cooks the Sunday roast but I have to limit him as I can't face the fallout in the kitchen afterwards! Everything is lightly smeared with grease and he uses 9 saucepans - just for the two of us.
Duck is now such a treat as we live in Duck Central.
Lamb - especially pink, with garlic and rosemary.
Chicken any which way.
Turkey - yum, can't get big ones in France so am denied my Boxing Day turkey sandwiches. We are thinking of raising them here for the Brits.
Pork, especially the crackling. The French don't do it like the English as the skin/fat is often removed, but you can get great sheets of it separately and it is divine when cooked as crackling.
Beef in France is nothing like British beef, so I really long for it, but even in UK it is increasingly difficult to find a good piece of topside. I have suggested to the famer next door that he imports a Hereford or Aberdeen Angus bull to cross with his beautiful Limousin herd. He just gives me a strange look.
Veal - another treat around here - and don't all shout. It is the Brits that do the wrong with veal. Next door is veal big time. When I said something about 12 week calves being used for veal in UK, and this was thought to be quite old and therefore good, Henri and his brother were horrified. Their calves are at foot until at least 6 to 7 months old, live out a grass all year, and taken into a lovely barn at night in the winter and read a bedtime story. And the meat is pink not white. I love to watch them in the field next to our house, and at night in summer with the windows open I can hear them munching the grass. Idyllic. And as for the little calves that skip around the field ........
Yorkshire puddings go with anything, including warm strawberry jam or golden syrup.
