What each ingredient does

Carrots: Provide the main body and sweetness of the soup.
Parsnips: Add body and a mellow, sweet flavour to the soup.
Thick gravy: Thickens the soup and adds richness and savoury depth.

The step that matters

Cook until tender, then add thick gravy and season well before serving.. Vegetables must be fully tender before adding gravy, since starch and cell structure soften only with sustained heat. Seasoning late lets the cook correct flavour once the thickened liquid is in place.
