a long time The History of foods 饼干起源于19世纪30年代的英国。大约在1831年，一艘英国帆船航行在法国附近，经比斯开湾（Biscay）时，遇飓风袭击，船员们逃到邻近的荒岛。风停后，船员回到船上寻找食物，把船舱内被海水泡湿了的面粉、砂糖、奶油等带回了荒岛。为了充饥，船员们将这几样东西混合在一起，捏成一个个薄薄的小饼，放在石板上烤熟，居然味道不错。 这些船员遇救回国后，为纪念这次历险，就用同样方法烤制了许多小饼分给纪念活动的人们吃。并命名为“比斯开小饼”（Biscuit）。这便是今天流行于全世界的饼干的来历。The History of BiscuitsThe biscuits were invented by accident!
Sandwich本来是英国东南部一个不出名的小镇，镇上有一位名叫John Montagu的伯爵，他整天沉溺于纸牌游戏中，已经到了废寝忘食的地步。仆人很难侍候他的饮食，便将一些菜肴、鸡蛋和腊肠夹在两片面包之间，让他边玩牌边吃饭。没想到John见了这种食品大喜，并随口就把它称作“sandwich”，以后饿了就喊：“拿sandwich来!” 其他赌徒也争相仿效，玩牌时都吃起sandwich来。不久，sandwich就传遍了英伦三岛，并传到了欧洲大陆，后来又传到了美国。sandwich已成为当今西方主要的快餐食品之一。 The History of SandwichesThe sandwiches were invented by accident!The History of Potato chipsGeorge CrumchefDo you know the history of the potato chips?
