Why it works: Spinach and pepper are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,400 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Spinach Au Jus
Ingredients
Directions
Prepare the spinach
Select young and tender spinach, or pick over and tear off only the tender parts of the leaves.
Put the spinach in a saucepan with 1 cup of boiling water and simmer for 10 minutes without covering.
Drain the spinach thoroughly in a colander, pressing out all moisture.
Chop the drained spinach finely, and optionally rub it through a colander to make a puree.
Season and serve
Add gravy or meat juice, butter, pepper, salt, and sugar to the spinach.
Heat the mixture in a saucepan until thoroughly hot and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the main body of the dish; cooking and draining concentrates it into a soft, tender mass.
- Butter
- Adds fat for a rich, smooth mouthfeel and carries flavour through the greens.
- Gravy or meat juice
- Adds savoury depth and salt-based flavour that complements the mild spinach.
- Sugar
- Adds a trace of sweetness that softens the bitterness of cooked spinach.
The step that matters
Draining the spinach thoroughly. Spinach holds a large amount of water. If moisture is not pressed out, the dish turns watery and dilutes the gravy and butter, so the flavour and texture suffer.
Swap the spinach
