Place chopped rhubarb, sugar, and lemon juice in a heavy-bottomed saucepan. Cook over medium heat, stirring occasionally, until the rhubarb softens and its juices thicken slightly to a syrup, about 8–10 minutes. Remove from heat and let cool slightly.

Slice white bread thinly and remove crusts. Optionally, spread a thin layer of softened unsalted butter on one side of each slice.

Dip bread slices into the warm rhubarb syrup to coat, then line the bottom and sides of a 1-litre pudding basin or deep bowl with soaked slices, ensuring full coverage. Spoon a layer of rhubarb mixture over the bread. Continue layering soaked bread and stewed rhubarb, finishing with a layer of fruit.

Cover the assembled pudding with plastic wrap or parchment paper. Place a small plate and a weight on top to press the layers together. Refrigerate for at least 1 hour, preferably overnight, to allow flavors to meld and the bread to fully absorb the syrup.

Remove the weight and wrapping. Loosen the edges with a knife if needed, then invert the basin onto a serving platter. Serve with golden custard sauce or a generous spoonful of whipped cream, either chilled or gently warmed.
