Why it works: Tarragon and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,547 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Curried Sweatbreads
Ingredients
Directions
Cut the veal sweetbreads into two-inch squares.
In a stewpan, heat the white stock with the onion juice, curry powder, tarragon vinegar, and butter.
Rub the butter with enough flour to thicken the sauce.
Once boiling, stir in the sweetbreads and let them simmer gently for 30-33 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal sweetbreads
- Provide the main protein, whose tender texture softens further with gentle simmering.
- Flour
- Thickens the butter and stock into a smooth, lightly bodied sauce.
- Butter
- Adds richness and fat that carries the curry flavour through the sauce.
- Curry powder
- Supplies the aromatic spice flavour that defines the dish.
- White stock
- Forms the liquid base of the sauce and cooks the sweetbreads gently.
The step that matters
Rub the butter with enough flour to thicken the sauce. Flour must be fully blended with the butter before it meets hot liquid, otherwise it clumps and the sauce turns lumpy instead of smooth.
Swap the onion
How well each one fits the dish's main ingredients (veal, tarragon, vinegar, butter, flour):
- Shallotfits better
- Chivefits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against veal, tarragon, vinegar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
