Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
In a large pot, heat the butter or oil over medium heat.
Add the mixed vegetables and sauté for 5 minutes.
Pour in the water or broth and bring to a boil.
Reduce heat and simmer for 20 minutes until vegetables are tender.
Season with salt and pepper before serving.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mixed vegetables
- Provide the bulk of the soup and its flavour as they soften and release sugars.
- Water or vegetable broth
- Forms the liquid base that cooks the vegetables and carries flavour through the soup.
- Butter or oil
- Carries heat into the pot and sautés the vegetables, adding fat and richness.
The step that matters
Simmer until the vegetables are tender. Simmering gently cooks vegetables through without breaking them apart. Stopping too early leaves them firm and starchy, while boiling too hard can make them mushy and cloudy the broth.
Swap the potato
How well each one fits the dish's main ingredients (carrot, celery, pepper, butter):
- Parsnipfits better
- Capsicumfits about as well
- Turnipfits about as well
- Potatothe original
Fit is the average pairing score against carrot, celery, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
