Why it works: Celery and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 3,467 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Stewed Pish with Lemon Sauce
Ingredients
Directions
Prepare the fish
Add enough water to a saucepan to cover the fish, then add the celery and onion.
Bring the water to a boil, then add the fish, butter, lemon juice, and salt.
Remove the fish when tender.
Make the sauce
Thicken the sauce with flour, then stir in the egg yolks carefully to avoid curdling.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they 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
- Fish
- Forms the main body of the dish, cooked gently in the simmering liquid until tender.
- Butter
- Adds richness and a smooth, silky mouthfeel to the cooking liquid and sauce.
- Lemon juice
- Provides acidity that brightens the flavour and gives the sauce its tang.
- Flour
- Thickens the sauce so it clings to the fish instead of running thin.
- Egg yolks
- Enrich and thicken the sauce, giving it body and a creamy texture.
The step that matters
Stirring in the egg yolks. Egg yolks thicken when heated but scramble and curdle if they get too hot or are added too quickly. Stir gently and keep the sauce below a simmer so it stays smooth.
Swap the onion
How well each one fits the dish's main ingredients (celery, fish, butter, lemon, flour, egg):
- Leekfits better
