Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pish Pudding
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.
Prepare the fish and potatoes
If using cold fish and potatoes, proceed; otherwise, boil blue smoked cod in water for 5 minutes.
Remove skin and bones from the fish and flake it into a basin.
Mash the potatoes and mix them with the flaked fish, pepper, and salt.
Bind the mixture with the egg.
Shape and bake
Grease a baking sheet with butter, shape the mixture into an 'S', and brush with egg or milk.
Bake at 400°F (200°C) until brown.
Transfer to a hot dish and garnish with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Blue cod
- Provides the main flaky protein and the body of the pudding.
- Potatoes
- Mashed starch that gives the mixture a soft, moist texture and holds the fish together.
- Butter
- Greases the baking sheet so the shaped pudding releases cleanly and browns evenly.
- Egg
- Binds the mixture and, brushed on top, promotes browning in the oven.
The step that matters
Bind the mixture with the egg. Egg proteins set when heated, so the egg must be evenly mixed through the fish and potato. Uneven binding can leave the pudding crumbly or loose once baked.
Swap the potato
