I have a nice piece of meat. I want to bake it deliciously so I can slice it for sandwiches later. Share your tried-and-true recipes: how to marinate, for how long, what to sprinkle on top and drizzle with. At what temperatures should I slow-cook it? In foil or a roasting bag – which is better to keep it from drying out? Thanks in advance! 🌺
