Why it works: Orange and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Bigarade Sauce
Ingredients
Directions
Prepare the peel
Cut the peel of half a Seville bitter orange into strips.
Place the strips in a saucepan and cover with water. Boil for 10 minutes, then drain using a sieve.
Make the sauce
In a saucepan, combine ½ pint of Espagnole sauce, ½ pint of rich stock or roast-meat gravy, and the juice of half the orange. Allow the mixture to reduce to half its quantity, then strain.
Add the orange peel, 1 teaspoon of lemon juice, and ⅓ cup of port wine. Season with pepper and coarse sea salt, then bring to a boil again.
Serve
Serve with roast wild duck or other game.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Espagnole sauce
- Forms the thick, savoury body of the sauce.
- Rich stock or roast-meat gravy
- Adds meaty depth and moisture, thinning the sauce as it reduces.
- Seville bitter orange peel
- Contributes aromatic oils and a bitter citrus flavour.
- Port wine
- Adds sweetness and fruity richness to balance the bitterness.
- Orange juice
- Adds citrus acidity and fresh fruit flavour.
The step that matters
Reducing the sauce to half. Reduction concentrates flavour and thickens the sauce. Stopping too early leaves it thin and bland, while over-reducing makes it salty and syrupy once the port and seasoning are added.
Swap the bitter orange
How well each one fits the dish's main ingredients (sauce, meat, orange, lemon, port wine, pepper):
- Limefits better
- Figfits better
- Cherryfits better
- Bitter orangethe original
Fit is the average pairing score against sauce, meat, orange, lemon, port wine, pepper. Candidates are from the same food group and used in at least 100 recipes.
