I had always thought that was "polk salad" as in the Elvis song Polk Salad Annie.
I think the various types of cabbage tend to be under-rated in the scoff stakes. I imagine mostly because of the way the poor little things were cooked by our female forebears,, schools, the armed forces and various other institutions. Boiled for nine hours.
I only found out cabbage was green in my early twenties. Thanks for all the grey slop Mum.
Do you think it is wise to trust the spelling of a Mississippi born Army Sergeant?
