Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Crecy Soupe a LA Reine
Ingredients
Directions
Prepare
Scrape and slice the carrots thinly, removing the exterior red but not the center.
Peel and slice the onion and turnip, and chop the ham and parsley.
Make the soup
In a stewpan, melt the butter and fry the vegetables and ham until light yellow.
Add the sliced carrots and water, and stew until tender.
Mix in the flour smoothly, then add the stock.
Season with salt and sugar, and bring to a boil for 15 minutes.
Pass the soup through a fine sieve and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Form the body and sweet flavour of the soup once stewed and sieved.
- Butter
- Carries the frying of the vegetables and ham, adding richness and browning gently.
- Flour
- Thickens the stock so the sieved soup becomes smooth and velvety.
- Stock
- Provides the main liquid and savoury depth of the soup.
- Onion
- Adds savoury, aromatic depth when fried in butter.
The step that matters
Mixing in the flour smoothly. Flour clumps if added to hot liquid without being blended first, leaving lumps that a sieve may not fully remove. Mixing it smoothly into the stewed vegetables before adding stock lets it thicken evenly.
