My (half Welsh) Grandmother used to make bread pudding unlike any I have seen since. Unlike the bread and butter puds I see now where you can see distinct slices of bread, I think she used to crumb stale bread, mix it with mil(?) and dried fruit, then bake it. There was no semblance of sliced bread and it was more like a stiff custard. I must try and work out what she did and try it sometime
