You can use either a board or a plate as long as it is large enough and sits firmly on a surface that is nonslip. The platter or board used should be almost flat, as carving in a deep dish is virtually impossible.
If the table is slippery and the serving plate is china, put a cloth mat or folded napkin underneath to keep the dish from moving. And while it may look attractive to put the potatoes and other vegetables around the joint, this can make carving awkward and messy.
Another essential requirement for carving is a razor-sharp knife and a carving fork with a guard to prevent the from knife slipping.
