Why it works: Potato and milk are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 3,611 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Dinner. — Roast Ducks
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 ducks
Preheat the oven to 400°F (200°C).
Season the ducks with coarse sea salt.
Roast the ducks in the oven until cooked through.
Prepare the sides
Prepare the stuffing and cook it according to your recipe.
Boil the new potatoes until tender.
Steam or boil the sprouts until bright green.
Serve
Serve with gooseberry tart and custard made from eggs and milk.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ducks
- Provide the main meat, whose fat renders and crisps the skin during roasting.
- Eggs
- Thicken the custard by setting as their proteins coagulate with gentle heat.
- Milk
- Forms the liquid base of the custard, adding richness and body.
The step that matters
Roast the ducks until cooked through. Duck has a lot of fat under the skin and dense meat, so it can look done on the outside while the inside is still undercooked. Checking that the meat is fully cooked, and letting the fat render, matters for both safety and texture.
Swap the gooseberry
How well each one fits the dish's main ingredients (potato, egg, milk):
- Vanillafits better
- Coconutfits better
- Lemonfits better
- Gooseberrythe original
Fit is the average pairing score against potato, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
