Drain and flake the salmon.

In a mixing bowl, combine lemon juice, salt, and pepper; then add the flaked salmon.

In a separate bowl, beat the eggs yolks and add to the salmon mixture.

Add bread crumbs, melted butter, and diced celery to the salmon mixture.

In another bowl, beat the egg whites until stiff peaks form.

Gently fold the stiffly beaten egg whites into the salmon mixture.

Grease a loaf mold.

Pour the salmon mixture into the greased mold and cover with buttered bread crumbs.

Place the mold in a pan of hot water (water bath).

Bake in a preheated 350°F (175°C) oven for 30 minutes.

Remove from oven and let cool slightly.

Unmold the salmon loaf and serve.
