Tried it last night,
Soaked the liver in milk for 2 hours, dried it off and then floured it and fried it lightly.
Placed it in a casserole dish and then fried off some onions and bacon, then added some HP sauce, tomato puree and gravy powder.
Put it in the oven for 2 hours at about 160.
And it was terrible.
It tasted lovely but I just couldn't stand the texture of the liver (it reminded me of really cheap pressed together mechanically reclaimed meat due to its lack of any grain or texture to it)
