Why it works: Pepper and carrot match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 14,555 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Giblet Soup
Ingredients
Directions
Make the stock
Combine the veal, giblets, mace, pepper, salt, onions, carrots, and water in a pot.
Bring to a boil and simmer for 3 hours.
Strain the soup and set aside the strained liquid.
Finish the soup
Cut up the gizzard and slice the liver, then add them back to the soup.
Mix the flour with the butter until smooth in a bowl.
Stir the flour‑butter mixture into the soup along with the red wine.
Bring the soup to a boil once more before serving.

Butter and flour share little aroma chemistry, yet 124,287 recipes mention both: they likely 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
- Butter
- Adds richness and fat, and with the flour gives the soup a smooth, slightly thickened body.
- Flour
- Thickens the soup when cooked with the butter, giving it body.
- Red wine
- Adds acidity and depth of flavour to the finished soup.
- Veal
- Releases gelatin and savoury flavour into the water during simmering, enriching the stock.
- Onions
- Contribute sweetness and aromatic flavour to the stock as they cook down.
The step that matters
Mix the flour with the butter until smooth. Mixing flour and butter into a smooth paste before adding it to hot liquid prevents lumps; the starch then thickens the soup evenly as it heats.
Flavor stand-ins for the mace
How well each one fits the dish's main ingredients (veal, pepper, onion, carrot, butter, flour, red wine):

- Celerybetter flavor fit
- Macethe original
Fit is the average pairing score against veal, pepper, onion, carrot, butter, flour, red wine. 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).
