Why it works: Asparagus and ham match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and 100 recipes mention both. Both carry 2-octenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the asparagus
Blanch the asparagus pieces in boiling water until tender.
Add the blanched asparagus to the good stock and strain the mixture.
Make the vegetable base
In a stewpan, combine the carrots, turnips, onions, celery, and cabbage with butter and ham.
Cover and stew briefly.
Add enough stock to cover the vegetables and boil until soft.
Add mint leaves and the crust of a roll.
Pound the mixture.
Add the peas and finish
Boil a quart of green peas.
Strain the boiled peas.
Pound the strained peas.
Mix the pounded peas with the vegetable mixture and pass through a sieve.
Heat the soup and season with salt, pepper, and sugar.
Garnish with young boiled peas before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green asparagus
- Provides the main flavour and bright green colour of the soup.
- Green peas
- Thicken the soup when pounded and add body and sweetness.
- Butter
- Adds fat and richness, carrying flavour through the stewed vegetables.
- Onions
- Build savoury depth as they soften during stewing.
- Crust of a roll
- Helps thicken the soup, giving it a smoother body.
- Lean ham
- Adds savoury, meaty flavour to the vegetable base.
The step that matters
Pound and sieve the peas and vegetables. Pounding breaks down cell walls so the soup becomes smooth and thick; passing it through a sieve removes fibres and any remaining lumps, giving a fine texture.
Flavor stand-ins for the onion

Fit is the average pairing score against asparagus, bread, carrot, turnip, celery, cabbage, lettuce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
