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 ↓
Mayonnaise De Ris De Veau
Ingredients
Directions
Prepare the sweetbreads
Clean the sweetbreads.
Boil the sweetbreads for 20 minutes.
Remove all skin and fibers, then set aside to cool.
Cut the cooled sweetbreads into small, even dice.
Prepare the lettuce and plate
Crisp the lettuce by washing and drying it thoroughly.
Rub the bottom of a soup plate with the cut side of half an onion.
Add a little tarragon vinegar to the plate.
Assemble the salad
Mix the mayonnaise with the diced sweetbreads.
Rub a small crust of bread with onion. Mix the bread through the sweetbreads.
Arrange the mixture in a mound in a salad bowl, surrounded by a row of lettuce leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the main meaty texture and body of the salad.
- Mayonnaise
- Adds fat and moisture, binding the diced sweetbreads into a creamy mixture.
- Lettuce
- Adds crisp texture and fresh contrast to the rich mixture.
- Tarragon vinegar
- Adds acidity and a sharp aromatic note that cuts the richness of the mayonnaise.
The step that matters
Remove all skin and fibers from the sweetbreads. Skin and fibrous membranes stay tough and chewy when cooked, so leftover pieces spoil the texture of the diced salad. Removing them after boiling, while the sweetbreads are still warm and easy to peel, gives a tender result.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (lettuce, tarragon, vinegar, bread):
- Mustardfits better
- Beetrootfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against lettuce, tarragon, vinegar, bread. Candidates are from the same food group and used in at least 100 recipes.
