Why it works: Haddock and ketchup share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 23 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Baked Haddocks
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.
Prepare
Place the cleaned haddocks on a flat dish.
Surround the fish with a border of mashed potatoes.
Add a bit of butter and a little salt inside each fish.
Glaze and bake
Glaze the fish with beaten egg.
Dot the tops of the fish with bits of butter.
Garnish with potato balls.
Bake at 350°F (175°C) for 30 minutes.
Finish and serve
Pour melted butter and ketchup over the fish before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the dish, cooking through gently in the oven.
- Mashed potatoes
- Form a soft border that holds the fish and adds starchy body to the dish.
- Butter
- Adds richness and moisture, keeping the fish from drying as it bakes.
- Egg
- Beaten egg glaze sets on the surface and promotes light browning.
- Ketchup
- Adds sweetness and acidity to the sauce poured over the fish.
