Forms the liquid base that carries the flavor of the whole soup.
Carrots
Soften during cooking and release natural sweetness into the broth.
Parsnips
Soften during cooking and add a mild, sweet earthy flavor to the broth.
Potatoes
Release starch that lightly thickens the broth and gives it body.
Onions
Soften and add savory depth and aroma to the broth.
Extract of beef
Adds savory, meaty flavor and deeper color to the broth, as the record states.
