The manager was very proud of being able to provide any dish, no matter how 2 it was. At the bottom of the 3 , there was a notice that said, “If you do not see the dish you need on this menu, please tell us and we will add it to the menu right away.” The man 4 the menu and decided to make sure if it was true. He would order 5 that was very unusual. When a waiter came up to take his order, he said, “You say you can serve any dish, even if it’s not on your longest menu in the world.” “That is 6 , sir. We are able to meet everyone’s requirements.” “Well,” the man said, “bring me a sandwich with two elephant ears. Indian, not African.” The waiter wrote down in his paper: Two Indian elephant ears on toast (烤面包片).展开更多

First, beat the eggs in a bowl until they am Well mixed. Add some salt. Cut the tofu into small cubes and put them into the bowl as well. Then put the bowl in a steamer and steam for about ten minutes. When the eggs become a soft jelly, turn off the stove and let the dish cool before garnishing it with minced coriander, scallion and a teaspoon of sesame oil (or chili oil if you prefer). Serve. I served the steamed eggs with tofu to my family at supper. The展开更多
