Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Served Whole with White Sauce
Ingredients
Directions
Prepare the sweetbreads
Soak sweetbreads in tepid water for 15 to 30 minutes.
Place sweetbreads in cold water with a little salt and bring to a boil.
Once boiling, pour off the water and transfer sweetbreads to cold water until chilled.
Remove the pipe and skin using scissors, then cut sweetbreads apart.
Make the white sauce
In a saucepan, combine milk, flour, and butter, and bring to a boil.
Stir in the flour and butter mixture, add mace, and simmer for 5 to 10 minutes.
Add sweetbreads to the sauce and cook until pink disappears.
Use toothpicks to keep sweetbreads in shape, then place on a dish.
Garnish with parsley and pour the white sauce over and around them.
Remove the mace before serving.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Are the main protein, cooked gently until their pink colour disappears and they turn firm.
- Flour
- Thickens the milk into a smooth white sauce as it cooks with the butter.
- Butter
- Enriches the sauce with fat, adding richness and a smooth mouthfeel.
- Milk
- Forms the liquid base of the white sauce, giving it body once thickened.
The step that matters
Stirring the flour and butter into the milk. Flour thickens only when it is well dispersed and heated. Adding it in lumps or letting the sauce sit unstirred leaves clumps, so stir steadily as it heats.
Flavor stand-ins for the mace
How well each one fits the dish's main ingredients (milk, flour, butter, walnut, parsley):
- Nutmegbetter flavor fit
- Cinnamonbetter flavor fit
- Capersbetter flavor fit
- Macethe original
Fit is the average pairing score against milk, flour, butter, walnut, parsley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
