Why it works: Chervil and tarragon 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 ↓
To Preserve Beef-suet for Frying, or Paste
Ingredients
Directions
Prepare the suet
Melt 8 pounds of picked beef suet until dissolved.
Let the melted suet cool.
Skim off the fat and preserve it in a tightly covered pan in a dry place.
Make the herb paste
Wash and scald a handful each of chervil, tarragon, burnet, and chives in salt and water.
Pound the herbs finely in a mortar.
Add the yolks of 2 hard-boiled eggs, 1 tablespoon of sweet oil, and 1 tablespoon of chopped capers.
Mix these ingredients with ½ pound of fresh butter.
Set the mixture in ice to cool.
If the mixture is not sufficiently green, add a little spinach juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef suet
- Provides rich fat that firms when cooled, giving the paste body and a solid texture.
- Fresh butter
- Adds fat and creaminess, helping the herb mixture bind into a smooth, spreadable paste.
- Hard-boiled egg yolks
- Their fat and emulsifying qualities help bind the pounded herbs into a smooth paste.
- Chervil, tarragon, burnet, and chives
- Provide the aromatic flavour and the green colour of the paste.
The step that matters
Set the mixture in ice to cool. Cooling firms the fat so the paste holds its shape and spreads cleanly. If it warms, the butter and suet can separate or turn greasy, and the texture is lost.
Swap the spinach
The recipe marks spinach as optional. How well each one fits the dish's main ingredients (beef, butter, chervil, tarragon, chive, egg, capers):
- Shallotfits better
- Leekfits better
- Lettucefits better
- Spinachthe original
Fit is the average pairing score against beef, butter, chervil, tarragon, chive, egg, capers. Candidates are from the same food group and used in at least 100 recipes.
