British love their custard and essentially this a simple custard with apples. Great for beginning cooks to try and a great date night dessert.
Apparently the actual recipe for this dessert went down with the ship (understandable under the circumstances), but there are a few versions that attest to being close to the original.
My version is based on the recipe found in the Last Dinner on the Titanic. The portions in first class, particularly after nine courses, would likely be individual portions, making it more elegant and easier for the wait staff to serve.
