Why it works: Peas and asparagus match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 808 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
An Excellent Green Peas Soup
Ingredients
Directions
Cook the peas
Boil the peas with the carbonate of soda until tender, about 25 to 30 minutes.
Drain the peas and add them to the boiling stock.
Stew gently for 30 minutes.
Strain and finish
Pass the mixture through a fine sieve into a clean pan and bring to a boil.
Add salt if needed and the pounded sugar, skimming off any scum.
For an elegant variation, add the asparagus points just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the soup and give it its colour and flavour.
- Carbonate of soda
- Helps the peas soften and keep their bright green colour during boiling.
- Beef or veal stock
- Provides the liquid base and savoury depth of the soup.
- Pounded sugar
- Adds a little sweetness to balance the savoury stock and peas.
The step that matters
Skimming off any scum. Foam and impurities rise to the surface as the soup boils. Removing them keeps the soup clear and clean-tasting rather than gritty or murky.
Swap the asparagus
The recipe marks asparagus as optional. How well each one fits the dish's main ingredients (peas, beef, sugar):
- Asparagusthe original
- Leekfits about as well
- Potatofits about as well
- Carrotfits about as well
Fit is the average pairing score against peas, beef, sugar. Candidates are from the same food group and used in at least 100 recipes.
