Why it works: Potato and spinach work together. They rank in the top 5% of all ingredient pairs, and cooks put them together in 646 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Baked Haddock, Egg Sauce
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Clean the haddock and place it in a baking dish.
Beat the eggs and mix with cream, then pour over the fish.
Bake and cook sides
Bake for 30-40 minutes until the fish is cooked through.
Boil the potatoes until tender, then mash with butter.
Steam the spinach until wilted.
Serve
Serve the baked haddock with mashed potatoes and spinach.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main protein, which firms and turns opaque as it cooks through.
- Eggs
- Set when heated, thickening the cream into a custard-like sauce over the fish.
- Cream
- Adds moisture and richness, keeping the egg sauce smooth rather than grainy.
- Potatoes
- Starch that softens when boiled and mashes into a soft, creamy side.
- Butter
- Adds fat and flavour to the mashed potatoes, making them smoother and richer.
The step that matters
Pour the egg and cream mixture over the fish. Eggs set at around 160°F when heated gently; too much heat or a long bake can curdle the sauce and make it grainy, while the fish must still reach a safe internal temperature.
Swap the apple
How well each one fits the dish's main ingredients (haddock, egg, cream, potato, spinach, butter):
- Lemonfits better
