In page Scotch broth:

"

In the early 19th-century cookery book A New System of Domestic Cookery by Maria Rundell, "Scotch Mutton Broth" is made with mutton neck, skimmed and simmered around an hour before good-quality cuts of bone-in mutton are trimmed of their fat and added to the soup. After several hours, soup vegetables are added—turnips, carrots and onion—and simmered until just tender; finally, pre-soaked Scotch barley is added. The soup is served with a garnish of fresh parsley.[citation needed]
