In classical French cooking, brown stock is made with veal bones for a delicate-bodied soup; here, beef is added for a deeper flavor. To make a traditional version, simply replace the beef with more veal bones. This recipe is from the "Martha Stewart's Cooking School" cookbook.
In Vietnam, pho, as this rice-noodle soup is known, is often enjoyed for breakfast. Nutritionists recommend incorporating red meat into one's diet just as it's used here -- in small portions and as a complement to other foods. The soup also includes bean sprouts and a handful of fresh herbs. The stock needs to be refrigerated for at least six hours; make it a day ahead.
