MY Granmother used to eat tripe also with milk and onions. I used to buy the tripe for her in the butchers in the centre of Newcastle as the butchers in the neighbourhoods didn't seem to sell it. By the way she was always eating it and she lived until she was 100 and 5 months old (Got telegram from the Queen). Maybe eating the tripe had something to do with it. I don;t have the recipe but maybe if you google it. Hope your find a recipe soon.!
