Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Young spinach leaves
Forms the leafy base of the salad, providing bulk and a fresh, tender texture.
Hard-boiled eggs
Add protein-rich body and a mild, creamy contrast to the sharp dressing.
Vinegar
Adds acidity that brightens the flavour and balances the oil.
Oil
Carries flavour and coats the leaves, giving a smooth, glossy mouthfeel.

The step that matters

Drying the spinach thoroughly. Water left on the leaves dilutes the dressing so it slides off instead of clinging. Oil and vinegar do not mix with water, so drying well lets the dressing coat each leaf evenly.

Swap the onion

How well each one fits the dish's main ingredients (spinach, egg, vinegar, pepper):
