Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Sweetbreads with Tomatos
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the sweetbreads
Place sweetbreads in scalding water for a few minutes, then transfer them to cold water to cool.
Remove the skin without breaking the sweetbreads.
Stew and brown
Combine sweetbreads, water, and seasonings in a stew pan and cook over low heat.
Mix browned flour with a small piece of butter until smooth, then add the mixture to the stew pan with mace.
Stir well and adjust seasoning if necessary.
Let stew for 30 minutes.
Transfer the stew pan to a 400°F (200°C) oven until sweetbreads are browned.
Make the tomato sauce and serve
In a separate pan, thicken stewed tomatoes with flour and butter, seasoning to taste.
Strain the tomato mixture into the stew pan.
Bring to a boil and stir until done.
Pour the sauce over the sweetbreads.
Serve hot in a heated dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, meaty main body of the dish.
- Browned flour
- Adds a toasted, deeper color and flavor to the stew.
- Stewed tomatoes
- Add acidity and body to the sauce.
- Flour
- Thickens the tomato mixture into a smooth sauce.
- Butter
- Adds richness and fat to the thickened sauce and stew.
The step that matters
Thickening the tomato sauce. Flour must be cooked smoothly into the butter and liquid while stirring, and the sauce brought to a boil, so it thickens evenly without lumps or a raw floury taste.
Swap the mace
How well each one fits the dish's main ingredients (pepper, flour, butter, tomato):
- Parsleyfits better
- Thymefits better
- Turmericfits better
- Macethe 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.
