On 13 June 1947, when she was 22 years old and recently married, my mother started a recipe book in a looseleaf 4-ring binder. Some of them are in her handwriting, and some are typewritten. These recipes were used in the decade after the end of World War 2, when many items of food were in short supply. Some were even rationed until the early 1950s.
Ingredients are in Imperial Measures.
