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 ↓
Potage Aux Aspekges, or Asparagus Soup
Ingredients
Directions
Prepare the vegetables
Scrape and cut the asparagus into pieces and place them in a basin of clear water.
In boiling water, add the lettuces, green onions, carrot, parsley, and peas with salt; boil briefly and skim.
Transfer the vegetables to a fine sieve to drain.
Make the soup
In a large clean saucepan, melt the butter and add the drained vegetables; stir until completely mashed.
Gradually add the beef consommé while stirring gently.
Once well combined, add the sugar and a little more salt, then strain through a fine sieve.
Mix in the beef stock and bring to a boil; cook for 1.5 hours before serving.
Add the blanched asparagus cut into small pieces 30 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Gives the soup its main flavour and tender pieces of vegetable texture.
- Butter
- Adds richness and carries flavour as the vegetables are mashed into the base.
- Beef stock
- Provides the main liquid and savoury body of the soup.
- Beef consommé
- Adds concentrated beef flavour and a clearer, more savoury character to the soup.
- Peas
- Contribute sweetness and soft body when cooked and mashed into the base.
- Cabbage lettuces
- Add bulk and mild vegetal body that thickens the soup when mashed.
The step that matters
Straining through a fine sieve after mashing. Mashed vegetables contain fibres and solids that stay cloudy unless fully strained. Pressing and sieving removes them, giving a smooth, even texture in the finished soup.
