After my mother's comment on the post about meatballs, I had to google baked mince rolls. Now of course everyone wanted to give me sausage roll recipes. I also found this:
Baked Mince Roll
This is quite a dainty dish which can be made out of the scraps of cold beef, ham or tongue. Pass the meat through a grinding machine, add bread crumbs, season with parsley, pepper and salt and work in a beaten egg. Make a nice short crust, roll it out, place the meat upon it, and fold the pastry over so as to make a neat roll. Bake 1-2 hour and serve with thick brown sauce. Mrs. William Morton.
And a bread thing by Nigella, in which a sort of foccaccia dough is rolled up with a savoury mince filling. Which looks sort of tasty but if I am going to have some white floury concoction with my savoury mince then my nostalgic childhood longing demands it be Yorkshire pud.
Anyway I rather suspect Mum meant something more along the lines of this, in which mince is bulked up with breadcrumbs and bound with an egg, then rolled up like a swiss roll with a filling (though I can't imagine there would have been any pine nuts or grilled peeled capsicum in a 1950s Tasmanian version. I wonder if Mum remembers the recipe, and if she will include it in the comments?
