What each ingredient does

Onions
Provide the mild, sweet body of the soup and soften when simmered.
Consommé
Forms the clear, savoury liquid that carries the flavour of the soup.
Cooked fine peas
Add sweetness, colour and a soft texture to the soup.
Croutons
Add crisp contrast to the soft onions and peas.

The step that matters

Cooking the onions in the consommé until tender. Undercooked onions stay firm and taste raw, while overcooked onions break down and release starch that clouds the clear consommé. Stop when they are just tender and still hold their shape.
