Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Brown the base
In a large iron kettle, combine the fat, suet, and bacon. Fry until golden brown, stirring often.
Add the shredded chestnuts, diced onions, celery, and potato strips. Fry until the vegetables are golden brown.
Make the stew
Stir in the minced veal and tongue, cooking for 5 minutes. Season with salt and white pepper.
Sift the flour over the mixture, stirring until smooth and rich brown.
Add the water and let it simmer slowly for 1 hour.
Serve
Serve with bowls of cooked rice, prepared until dry and flaky.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Provides the main meaty body and chew of the stew.
- Bacon
- Renders fat and adds smoky, savory flavor to the base.
- Suet
- Adds rich fat that carries flavor and gives a richer mouthfeel.
- Flour
- Browns in the hot fat and thickens the liquid into a smooth sauce.
- Onions
- Soften and turn sweet and golden, building aroma in the base.
- Potatoes
- Hold their shape in the simmer and add starch that gives body.
The step that matters
Sifting and stirring the flour. Flour dropped into hot fat clumps easily if not sifted and stirred constantly. Cooking it until rich brown develops color and flavor, and it thickens the liquid evenly once water is added.
Swap the white pepper
How well each one fits the dish's main ingredients (veal, chestnut, meat, onion, celery, potato, flour):
- Turmericfits better
- Thymefits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against veal, chestnut, meat, onion, celery, potato, flour. Candidates are from the same food group and used in at least 100 recipes.
