Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Celery, Ragout of
Ingredients
Directions
Prepare the celery
Wash and trim the celery, cutting each stick into 2-inch pieces.
Cover with cold water, bring to a boil, and drain the water.
Add the stock and chopped Spanish onion, season with salt and pepper, and cook gently for about 30 minutes.
Make the sauce
Meanwhile, skin the button onions and fry them slowly in hot butter until tender, then drain and keep warm.
Add the flour to the remaining butter and fry for a few minutes without browning.
Remove the celery, then add the strained stock and milk to the roux, stirring until boiling.
Season to taste, add the cream and parsley, and mix well.
Serve
Arrange the celery in a circle on a hot dish, pour the sauce over it, and pile the fried onions in the center.
Sprinkle the remaining parsley on top and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Forms the main body of the dish and gives it its tender, fresh vegetable texture.
- Flour
- Thickens the butter and stock into a smooth sauce when cooked as a roux.
- Butter
- Carries flavour and enriches the sauce, and is used to fry the onions and make the roux.
- Milk
- Adds body and mild sweetness to the sauce, softening its savoury flavour.
- White stock
- Gives the celery and sauce their savoury base and liquid for the sauce.
- Cream
- Adds richness and a smooth, velvety finish to the sauce.
The step that matters
Adding the stock and milk to the roux. Flour must be cooked in fat without browning so it thickens well and tastes raw-free. Adding liquid too fast or without stirring can cause lumps, so stir constantly until the sauce boils and thickens smoothly.
Swap the onion
How well each one fits the dish's main ingredients (celery, milk, cream, parsley, butter, flour, pepper):
