Why it works: Tarragon and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 824 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Savoury, or Aspic Jelly
Ingredients
Directions
Prepare the base
Tie thyme and parsley into a bouquet.
Place carrots, celery, and bouquet in a stewpan.
Boil gently for 6 hours.
Strain through a soup cloth, skimming off any fat.
Prepare the stock a day in advance and refrigerate.
Make the aspic
Bring the stock and reserved calf's-foot stock to the fire.
Wash them clean of grease.
Melt both stocks together.
Test firmness by placing a little on ice.
If not firm, add more calf's-foot stock or gelatin.
Add tarragon vinegar, green tarragon, chervil, peppercorns, mace, and salt to the melted stock.
In a bowl, beat the eggs well. Add 1 pint of warm stock and whisk together.
Combine with the stock on the fire, including the eggshells.
Bring to a slow boil on a hot plate to prevent burning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites bind to impurities and clarify the stock as they cook.
- Calf's-foot stock or gelatine
- Gelatin sets the liquid into a firm jelly when chilled.
- Carrots
- Slow boiling draws out their flavour and colour into the stock.
- Tarragon vinegar
- Adds acidity that brightens the flavour of the savory jelly.
The step that matters
Bring to a slow boil. Boiling too fast or on too hot a surface can scorch the stock and cloud it. Egg whites need gentle heat to rise and form a raft that clarifies the liquid.
