Why it works: Celery and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓

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 filling
Boil the rabbit joints in 2 quarts of water with onion, celery, carrot, and herbs until tender.
Remove the rabbit from the pot, discard the bones, and slice the meat thinly.
In a bowl, mix the milk, cheese, chopped onion, salt, pepper, and egg yolk.
Assemble and bake
Line a dish with boiled macaroni.
Fill it with rabbit slices.
Pour the cheese sauce over the top.
Cover with a thin layer of puff pastry.
Bake at 400°F (200°C) for 1 hour.
Serve
If possible, turn it out and serve with brown or tomato sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Provides the main meat, which becomes tender through long simmering in water.
- Egg yolk
- Helps the cheese mixture set into a binding custard when baked.
- Cheese
- Adds richness and savoury flavour to the milk-based sauce.
- Milk
- Forms the liquid base of the cheese sauce, adding moisture and creaminess.
- Puff pastry
- Forms a crisp, browned top layer that seals in the filling.
The step that matters
Cooking the cheese sauce with the egg yolk. Egg yolk thickens when gently heated, but if the custard is baked too hot or too long it can curdle or turn grainy. A moderate oven and a firm, set centre keep the sauce smooth.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, celery, carrot, cheese, milk, pepper, egg):
- Capsicumfits better
- Potatofits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against rabbit, celery, carrot, cheese, milk, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
