However, even icons like the classic roastie can be riffed on - welcome to the stage out Cacio e Pepe Roasties. These are simply roasted with the latter addition of cheese and pepper - the cheese forms lacy little cheese skirts around the potatoes, the pepper gives heat.
Preheat the oven to 180°C.
Peel the potatoes and cut into large, roastie shaped pieces - aim to give the roasties flat sides if possible to enhance crispiness later on.
Place them in a large pot of cold water along with the salt and bring to a simmer. Remove them from the pan when the outsides are fluffy but they aren't completely cooked through.
While the potatoes are simmering, pour the goose fat into a large sturdy roasting tray and place it back in the oven to heat up.
Drain the potatoes in a colander and knock them about a bit of fluff them up even further - fluffiness increases surface area which increases crispiness.
Roast them for around an hour, tossing them at intervals.
Use the fine grating part of a box grater to grate the cheese over the potatoes and season liberally with the black pepper, then return to the oven to melt the cheese.
Serve dusted with more cheese and pepper.
