Why it works: Spinach and onion match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,336 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Milk and Vegetable Soup
Ingredients
Directions
Cut the vegetables into small pieces.
In a double boiler, cook the vegetables and bread crumbs in the skim milk.
For larger quantities, use a meat chopper to grind the vegetables and bread crumbs, which will help absorb the juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Skim milk
- Forms the liquid base and keeps the soup moist while the vegetables cook.
- Spinach or lettuce leaves
- Supplies the vegetable flavour and body of the soup.
- Bread crumbs
- Absorb liquid and thicken the soup slightly.
- Onion
- Adds a savoury aroma and background flavour.
The step that matters
Cook in a double boiler. Milk scorches and sticks quickly over direct heat. Gentle indirect heat from a double boiler warms the milk evenly, so the soup stays smooth and does not burn on the base of the pan.
