A Russian fish pie packed with salmon, rice, hard-boiled eggs and mushrooms, then wrapped in puff pastry to form a pillow shape. A great dish for a party, especially when served with warm beurre blanc.
Cook the rice until tender, then drain well. Hard-boil 3 of the eggs for 10 minutes, place in a bowl of iced water to cool quickly, then coarsely grate or finely chop.
Melt half the butter in a pan and add the spring onion. Cover and cook for 4 minutes over low heat until soft and translucent. Season and set aside.
