Rhubarb and lemon croissant pudding recipe

This is a luxe, croissant-based take on classic bread and butter pudding. The success of the recipe depends on using great-quality croissants, ideally slightly stale so they soak up the custard without collapsing. The double tang of lemon and rhubarb cuts through the richness, bringing brightness and balance to the soft sweetness of the pudding.
