Why it works: Pepper and nutmeg match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 13,015 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Sweetbreads with Tomatoes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the sweetbreads
Par-boil the sweetbreads and remove the skin.
Place them in a saucepan with water, salt, and pepper, and stew slowly.
Mix flour with butter and add nutmeg if desired; stir into the sweetbreads after 30 minutes of stewing.
Brown and make the sauce
Set the saucepan in the oven at 400 °F (200 °C) to brown the sweetbreads.
Pour the gravy into stewed tomatoes thickened with flour and butter; season with salt and pepper.
Strain the mixture into the stew-pan, bring to a boil, and stir until done.
Serve
Pour the sauce over the sweetbreads and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the main meat, which becomes tender and succulent when slowly stewed.
- Flour
- Thickens the gravy so the sauce coats the sweetbreads rather than running off.
- Butter
- Adds richness and body to the flour thickening, smoothing the sauce.
- Stewed tomatoes
- Add acidity and body, forming the base of the sauce.
The step that matters
Thickening the sauce with flour and butter. Flour must be cooked with butter and stirred into liquid until it boils to gelatinize its starch. If it is not fully cooked and stirred, the sauce stays pasty or lumpy and tastes of raw flour.
Swap the nutmeg
The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (pepper, flour, butter, tomato):
- Parsleyfits better
- Thymefits better
- Turmericfits better
- Nutmegthe original
Fit is the average pairing score against pepper, flour, butter, tomato. Candidates are from the same food group and used in at least 100 recipes.
