I got these from a Butcher's shop in the middle of nowhere once, and they were bloody lovely. After much searching and tweaking I got the recipe manageable and yummy.
You can use any kind of mince, I've only made them with Turkey mince, as the missus is a semi-veggy, but it's equally workable with Beef mince.
1lb turkey/beef mince
1 cup water
2 cups grated cheese
2 cups flour
1/4 cup butter
4 tsp baking powder
1 cup evaporated milk
1/2 tsp salt
1 pack beef stroganof seasoning mix (or feel free to use whatever flavouring you want, yes I know it's cheating.)
Brown meat, drain off fat.
Add water and seasoning mix, heat to boiling.
Boil gently, uncovered for 20-30 minutes or until all the water's evaporated.
Remove from heat, stir in 1 cup of cheese.
Combine flour, baking powder and salt into a mixing bowl, cut in the butter. Stir in the evaporated milk.
Knead the dough 10-15 times on a floured surface.
Roll out to an 18" x 10" rectangle, then spread the meat over the dough, leaving a gap round the edges to seal.
Roll up the pinwheel, like a swiss roll, or a home-made meat telescope.
Cut into 1 1/2" slices, place into a baking dish.
Bake at 180C/Gas Mark 6 for 25 mins.
Sprinkle remaining cheese over the pinwheels and bake for 2 more minutes so the cheese melts.
And that's it. V yummy in your tummy.
