We sometimes had Surprise Peas. They came in a packet and were crinkly if I remember right Witzend but not like the peas that you soaked with a white tablet of something. Mum cooked mostly from scratch so it was veg from the garden and meat from the village butcher. We did have days where we usually had the same meal and we always had a cooked meal at school too.
Can’t say I remember any of those - I don’t know what ‘Surprise Peas’ were, but I do remember having tinned ones.
My mother (almost always pretty skint) cooked virtually everything from scratch. The only tinned foods I really remember were baked beans, the occasional tin of pilchards, and equally occasional tinned fruit.
