Shared aroma: isobutyraldehyde (malty, green).
Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Sweetbreads
- The main protein; slow cooking in butter keeps the pieces tender and moist.
- Butter
- Fat that carries flavor and gives the dish richness, and cooks the sweetbreads gently.
- Flour
- Starch that thickens the liquid into a smooth sauce as it heats.
- Broth
- Liquid that combines with the flour and butter to form the sauce.
The step that matters
Adding the liquid to the flour and butter. Flour clumps if it is not fully mixed in before the liquid goes in. Stirring steadily while the mixture heats lets the starch disperse and swell evenly, giving a thick, smooth sauce instead of lumps.
