Egg Drop Soup is traditionally Chinese. Tomatoes are not. They were introduced less than 100 years ago, but nevertheless, they work wonderfully in this soup. PUT THE CHICKEN STOCK into a pot and bring to a simmer. If using fresh tomatoes, peel, seed and cut into 1-inch cubes. If using canned tomatoes, chop them into small chunks. Lightly beat the eggs, then combine them with sesame oil in a small bowl. Add the light soy sauce and salt to the simmering stock, and stir to mix them in well. Add the tomatoes and simmer for 5 minutes. Next, stir in the scallions, and then add the egg mixture in a very slow, thin stream. Using a chopstick or fork, pull the egg slowly into strands. (Stirring the egg in a "figure 8" works well.) Garnish with the finely chopped scallion tops. KEN HOM - PRODIGY GUEST CHEFS COOKBOOK
