Why it works: Fish and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,488 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Russian Fish Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the paste
Chop the butter into the flour.
Add baking powder and enough water to form a paste.
Roll out the paste into a long piece, fold into thirds, turn half round, and roll again.
Roll the paste to about 8 inches wide and 14 inches long.
Assemble the pie
Cut one end like an envelope flap and place the paste on a greased baking sheet.
Break the fish into flakes and place in the center of the paste.
Top with rice, salt, curry powder, and small bits of butter.
Fold the ends of the paste over the filling to resemble a large envelope.
Wet the edges to seal and decorate the paste.
Bake
Brush with beaten egg and bake at 400°F (200°C) for about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the paste that encloses the filling.
- Butter
- Chopped into the flour to add richness and tenderness to the paste.
- Baking powder
- Releases gas during baking so the paste rises and becomes lighter.
- Cod or other fish
- Forms the main filling, cooked gently inside the sealed paste.
- Boiled rice
- Adds bulk and soaks up moisture from the fish in the filling.
The step that matters
Sealing the envelope. If the edges are not wet and pressed firmly, steam and juices can escape during baking and the filling may leak or dry out.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
