Why it works: Carrot and parsnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,097 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Ingredients
Directions
Prepare the base
Combine the carrot, onion, lettuce, celery, and parsnip in a stewpan.
Add the butter or dripping and cover the stewpan tightly.
Cook on low heat until the vegetables begin to soften.
Simmer and strain
Pour in enough boiling water to completely cover the vegetables.
Season with salt and pepper.
Let the stock simmer until reduced to pulp, about 4 hours.
Skim and strain the liquid, setting it aside for use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter or dripping
- Adds fat that softens the vegetables and carries flavour into the stock.
- Onion
- Contributes sweetness and savoury depth as it softens and breaks down.
- Celery
- Adds aromatic, savoury flavour that forms the stock's background character.
- Carrot
- Adds natural sweetness and body as it cooks down into the liquid.
The step that matters
Cooking the vegetables on low heat in a covered pan. Gentle, covered cooking softens the vegetables in their own moisture and fat without browning or scorching. Scorching at the base would give the stock a bitter, burnt taste.
Swap the onion
How well each one fits the dish's main ingredients (carrot, lettuce, celery, parsnip, butter, pepper):
- Turnipfits better
