Why it works: Haddock and sauce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 200 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Haddock Pudding
Ingredients
Directions
Prepare the fish and potatoes
Boil the haddock in water with a little salt and vinegar for 10-15 minutes.
Remove the skin and bones from the haddock.
Cut the fish into small pieces.
Boil the potatoes in salted water until soft.
Sieve the boiled potatoes.
Shape and bake the pudding
Mix the sieved potatoes with the fish, raw egg, butter, pepper, and salt until well combined.
Shape the mixture as desired.
Place the shaped mixture in a buttered tin.
Bake the tin until golden.
Make the sauce and serve
Melt butter and flour in a saucepan over heat.
Gradually add the water from the haddock and milk, stirring for 10 minutes.
Add diced hard-boiled eggs and lemon juice to the sauce.
Pour the sauce around the fish pudding 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 pudding and gives it its flavor.
- Potatoes
- Add starch and softness, helping the mixture hold together and stay moist.
- Raw egg
- Binds the fish and potato mixture so it holds its shape when baked.
- Butter
- Adds richness and flavor to both the pudding and the sauce.
- Flour
- Thickens the melted butter into a roux that gives the sauce body.
- Milk
- Mixed with the fish water to make a creamy, smooth sauce.
The step that matters
Adding the fish water and milk to the roux. Adding liquid gradually while stirring keeps the flour smooth, so the sauce thickens evenly without lumps.
Swap the potato
How well each one fits the dish's main ingredients (haddock, vinegar, egg, butter, pepper, sauce, flour):
- Shallotfits better
- Mustardfits better
- Capsicumfits better
- Potatothe original
Fit is the average pairing score against haddock, vinegar, egg, butter, pepper, sauce, flour. Candidates are from the same food group and used in at least 100 recipes.
