Celery
Forms the main body of the soup and gives it its characteristic flavour.
Onions
Add sweetness and savoury depth as they soften during stewing.
Pearl barley
Releases starch as it cooks, thickening the soup and giving it body.
Stock
Provides the liquid that carries the flavour and cooks the vegetables.
