Mushroom, swede, potato, onion and rosemary pasties

They can be cooked from frozen, just bake for 1 hour instead. Always freeze them on baking parchment! You might think that they would come off a plastic chopping board easily, but you'd be wrong.

The salt is there to extract water from the mushrooms; after draining they should weigh about 400g.
