Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sweetbreads of Veal
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Parboil
Clean the sweetbreads.
Cover the sweetbreads with boiling water.
Add lemon juice, salt, onion, and peppercorns to the water.
Simmer the sweetbreads for 20 minutes.
Transfer the sweetbreads to cold water.
Prepare and bake
Cut the bacon into small squares.
Season the sweetbreads with salt and pepper.
Roll the sweetbreads in melted butter and flour.
String the bacon and sweetbreads on small skewers.
Place the skewers in a hot oven (400°F / 200°C) on a pan for about 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heart sweetbreads
- Provide the tender, delicate meat that forms the main body of the dish.
- Bacon
- Adds fat and salty flavor that bastes the sweetbreads as it renders in the oven.
- Melted butter
- Carries fat over the surface so the coating browns and turns golden in the oven.
- Flour
- Coats the sweetbreads so the butter clings and the surface crisps and browns.
The step that matters
Transfer the sweetbreads to cold water after simmering. Chilling after the simmer stops the cooking so the sweetbreads firm up and stay tender, and it makes them easier to handle and trim before coating.
Swap the lemon
How well each one fits the dish's main ingredients (onion, butter, flour):
- Avocadofits better
- Raisinfits better
- Coconutfits better
- Lemonthe original
Fit is the average pairing score against onion, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
