Cook the sausage in a big pan on medium heat. Break it up into small chunks as it cooks till it’s nicely browned.

Sprinkle the flour on the cooked meat and stir to cover it well. Keep it cooking for a couple of minutes, then slowly pour in the milk while stirring. Turn the heat up a bit till it bubbles, then lower it and let it thicken for about 5 minutes. Stir in salt, pepper, sage, and if you want, the red flakes.

Heat the oven to 375°F (190°C). Roll one puff pastry sheet and press it into a 9-inch pie dish, letting some hang over the sides.

Spread the sausage gravy over the pastry in the dish. Roll out the second pastry sheet and lay it on top. Cut off extra around the edges and press them together well. Make some small cuts on top so steam can get out.
