Bread 'n butter pud eternal

In his definitive Oxford Companion to Food, Alan Davidson admits that bread and butter pudding "can be made with something more exotic than plain bread... and can be enlivened by judicious spicing or by reinforcing the currants with plumper sultanas and mixed peel.

Variations abound: Rhubarb bread and butter pudding; ginger-jam bread and butter pudding; apple, rum and raisin bread and butter pudding; chocolate bread and butter pudding; marmalade spicy bread and butter pudding; white chocolate and raspberry bread and butter pudding; panettone bread and butter pudding; cherry bread and butter pudding; brioche bread and buetter pudding... full yet?
