Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the broth into a soft, sliceable mousse structure as it cools.
- Sweetbreads
- Provide the main savoury body and texture of the mousse.
- Whipped cream
- Adds lightness and a smooth, airy texture to the set mousse.
- Chicken broth
- Supplies the liquid that the gelatine sets, carrying the savoury flavour.
The step that matters
Stand the mixture in cold water until it begins to harden. Gelatine sets as it cools, so the mixture must thicken to a soft gel before folding in the whipped cream. Chilling too long makes it stiff and lumpy, while stopping too early leaves it too runny to hold its shape in the moulds.
Swap the lemon

Fit is the average pairing score against chicken, pepper, cream, watercress, olive. Candidates are from the same food group and used in at least 100 recipes.
