Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass
- Gelatin-rich fish protein that sets the liquid into a firm jelly as it cools.
- Veal gravy
- Forms the savoury liquid base that the gelatin sets into a glaze.
- Egg whites
- Collect impurities during clarifying, leaving the finished liquid clear.
- Tarragon vinegar
- Adds acidity and aromatic flavour to the savoury jelly.
The step that matters
Clarify with the egg whites. Egg whites must be whisked into the hot liquid and brought to a simmer so they coagulate and trap cloudy particles. Stirring too hard or skipping this step leaves the jelly murky.
