Correct. A blind coddle is when you had nothing else to put in it excepts spuds and onions. Talking with the mother there to ask her and she said sometimes it was nicer as a blind brown coddle. She actually laughed when I said it to her as she hasn’t heard that term in years. When she was growing and they would come home from to school to learn that it was a blind coddle for dinner there was a lot of FFS. She also mentioned it that might do ‘vegetarians’ these days.
Hold up! I got another call of her (she was talking to her brother) and his version of a blind coddle is there is no ‘stock’ added to it, its just boiled up in water and its own juices.
