Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Eels a LA Poulette
Ingredients
Directions
Prepare and cook
Skin the eels and cut them into 2–3 inch pieces.
Place them in a buttered stewpan large enough to hold them all on the bottom.
Season with pepper, coarse sea salt, and chopped parsley.
Cover with turned sauce and bring to a boil.
Reduce heat and simmer gently until cooked through, skimming as needed.
Finish and serve
Thicken with 4–5 egg yolks and stir in a walnut‑sized piece of butter and a little lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the sauce into a smooth, rich coating.
- Butter
- Melted into the sauce, it adds richness and a glossy finish.
- Lemon juice
- Adds a bright acidity that balances the richness of the sauce.
The step that matters
Thickening the sauce with egg yolks. Egg yolks set when heated, so the sauce must be kept below a boil while stirring in the yolks. If it gets too hot, the yolks scramble and the sauce turns grainy instead of smooth and velvety.
