Why it works: Lettuce and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 425 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Forms the main body of the filling, giving it savory bulk and a soft, spreadable texture when pounded.
- Tongue
- Adds rich, meaty flavor and a smooth, spreadable texture to the filling.
- Mayonnaise
- Adds fat and moisture, binding the pounded meat into a creamy spread.
- Anchovy paste
- Adds salty, savory depth that enhances the meat flavor.
The step that matters
Pounding the chicken and tongue to a paste. If the meat is left in coarse pieces, the filling will not spread evenly and will be less cohesive. Pounding breaks the fibers down so the mayonnaise can bind them into a smooth, uniform texture.
Swap the celery
How well each one fits the dish's main ingredients (chicken, pepper, anchovy, lettuce, tarragon, vinegar, bread):
- Capersfits better
- Parsleyfits about as well

- Celerythe original
Fit is the average pairing score against chicken, pepper, anchovy, lettuce, tarragon, vinegar, bread. Candidates are from the same food group and used in at least 100 recipes.
