Why it works: Onion and parsley match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 25,834 recipes mention both. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Nutmese À LA Crême
Ingredients
Directions
Prepare the sauce
Add onion to hot oil and simmer slowly without browning, for 10 m.
Add flour, rub smooth, pour on hot water, stir until smooth and well cooked.
Remove from fire, add parsley, salt and beaten egg.
Assemble and bake
Break nutmese into irregular pieces with a fork and mix it with the eggs, chopped coarse and ¾ teaspn. salt.
Put sauce, and nutmese with eggs, into pudding dish, in layers, with sauce on top.
Sprinkle with crumbs, corn meal or browned flour No. 1.
Bake in moderate oven until bubbling all through and delicately browned on top.

Flour and egg share little aroma chemistry, yet 104,138 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Nutmese
- Forms the main layered body of the dish, setting into a firm, sliceable base.
- Eggs
- Bind the layers and set during baking to give the dish a custard-like structure.
- Flour
- Thickens the hot water and oil into a smooth, stiff sauce that holds the layers together.
- Onion
- Softened slowly in oil to add mild sweetness and savoury depth to the sauce.
The step that matters
Cooking the onion slowly without browning. Gentle simmering softens the onion and sweetens it while keeping the oil pale. Browning would make the sauce taste bitter and darken its colour.

Fit is the average pairing score against flour, egg, parsley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
