Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Dissolves into the liquid to give the stock body and a slightly wobbly, clear texture when cooled.
- Onion
- Releases sweet, savoury flavour into the water as it simmers.
- Parsley
- Adds a fresh, herbal aroma and subtle green flavour to the stock.
- Bovril
- Adds concentrated meaty, savoury depth to the otherwise light liquid.
The step that matters
Boil until the gelatine dissolves. Gelatine must fully dissolve in the hot liquid; if it stays grainy or undissolved, it will not set or give the stock its intended body and clarity when cooled.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (onion, clove, parsley, tarragon):
- Thymefits better
- Marjoramfits better
- Fennelfits better
- Celerythe original
Fit is the average pairing score against onion, clove, parsley, tarragon. Candidates are from the same food group and used in at least 100 recipes.
