This is a recipe taken from a Delia Smith cookbook Once cooked, it will keep warm without coming to any harm, and it will also re-heat very successfully. And, yes, it does freeze well so, all in all, it's a real winner of a recipe. It's great because it can be made the day before and gently re-heated with no last-minute bother. It is a perfect accompaniment to venison, goose or pork (and if you have any left over it does wonders for bangers and mash).
