This pudding is pure nostalgia. Nostalgia must never be tinkered with, so I have kept it classic and traditional, it would be a crime to try to fancify this fresh-faced, fluffy and angelic nursery pudding. Almost a soufflé, almost a sponge, this pudding is truly a wonderful thing, quick to rustle up for hungry loved ones with a craving for something sweet. I can do the entire process with just two bowls and 20 minutes (I have often cooked it in the enamel bowl I mixed it in). Like those my mum made, it is cooked in the same dish as it is served in, a bonus for the washer-upper, and nicely unfussy. I often prefer a gratin dish on a table with scoops taken out of it, rather than fiddly individual portions.
Based on 4 servings, adjust as needed.
