Slow and low heat on top of chopped winter veg in a covered pot, with plenty of liquid.
And even better if you use a glass or ceramic pot rather than a metal one. Chop onions, carrots, swede, some but not much potato. Take the joint. Place in the pan. Add veg. Pour over the best part of a bottle of good red wine. add herbs and maybe a drizzle of olive oil. Season well.
Add lid, place in oven at about 150-170.
Return eventually, preferably many many hours later.
Remove meat from pan and place to one side. Remove veg and remaining liquid to a pan. Whoosh them up to make a thick sauce.
Decent horseradish, plenty of the sauce and thick slices of falling apart meat. Mmmmm!
