Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gravy or espagnole
- Forms the savoury base that the sauce is built on.
- Seville orange juice
- Adds acidity and bright citrus flavour that cuts the richness of game.
- Seville orange rind
- Contributes aromatic oils and a bitter citrus note to the sauce.
- Port wine
- Adds sweetness and depth, rounding out the savoury and sharp flavours.
The step that matters
Strain without pressing the onion. Pressing the onion forces starch and fine solids through the strainer, which thickens the sauce and makes it cloudy. Letting the liquid drain naturally keeps it thin and clear.
