Why it works: Onion and asparagus match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,212 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Cream of Asparagus Soup
Ingredients
Directions
Prepare the asparagus
Cut the tops off the asparagus.
Parboil the tops separately.
Cut the stalks into short lengths.
Make the soup
Cook the stalks slowly in the weak stock with the minced onion for one hour.
Strain the mixture.
Press the strained mixture through a colander.
Return the soup to the heat.
Cook the reserved tips until very soft in the liquid.
Pass the soup again through the strainer, rubbing all the pulp through the mesh.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Asparagus stalks
- Provide the main body and flavour of the soup as they break down during slow cooking.
- Weak stock
- Forms the cooking liquid that carries flavour and gives the soup its base.
- Onion
- Adds savory aroma and depth to the soup base as it softens in the stock.
The step that matters
Passing the soup through the strainer. Rubbing the pulp through the mesh breaks down fibres and yields a smooth texture; skipping or rushing this leaves the soup stringy and grainy.
