I forgot, when I want to make roasties with a difference, I par-boil the potatoes, drain and cool in a colander with a tea towel over them. Then I lightly scratch all the surfaces with a small fork to increase the surface area. I sift a little flour with loads of dry Colmans and gently roll the potatoes through the mix. Pop into very hot fat and gently baste them. They come out a treat :)
