That Marian as far as I recall when at Sea was Tinned Pudding,but possibly on other Ships made by the Cooks!
The Tinned stuff was quite good! I used to eat it with Ice Cream! Lovely! But it was traditional to eat it with Roast Beef,similar to the Yorkshire Pudding! I have a peculiar taste at times! LOL
Like eating Fresh Bread with Coke or Grapes! Yummy! Or my favourite Jelly Sandwiches!
I also liked Duff sliced with Marmalade or Black Current Jam!
Cheers
