Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 27,039 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the stock
Wash the skate and cut it into serving pieces.
Put the trimmings in a pan with water, bring to a boil, and skim.
Add the sliced onion and bouquet garni, then simmer for 30 minutes and strain.
Make the sauce and cook the skate
In a separate pan, heat the butter and stir in the flour until browned.
Add the strained stock, lemon juice, white wine, and skate pieces.
Season to taste and simmer for 15 minutes or until cooked.
Serve
Dish up the skate and strain the reduced stock over it.
Garnish with croutons and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Skate
- Forms the main body of the dish and becomes tender as it simmers gently in the stock.
- Butter
- Carries the flavour of the sauce and, with flour, forms the base for thickening.
- Flour
- Thickens the stock into a sauce when cooked in butter until browned.
- White wine
- Adds acidity and aroma that brighten the reduced stock.
- Onion
- Adds sweetness and savoury depth to the stock as it simmers.
The step that matters
Browning the butter and flour. Cooking the roux until browned gives the sauce its colour and nutty flavour, but it can scorch quickly, and scorched flour tastes bitter. Stir constantly and watch closely.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (butter, flour, lemon, white wine, pepper, bread):

- Onionthe original
Fit is the average pairing score against butter, flour, lemon, white wine, pepper, bread. 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).
