传说三国时候，刘备自东吴借兵之后，便带着人马攻打西川，留下关羽镇守荆州。这一年夏天，天气酷热，将士们顶着太阳练习武艺，个个汗流浃背。时间一长，许多将士心生内火，大便干结，小便赤黄，口干舌烂。关羽十分着急。一天关羽独自一人在书房沉思默想，不觉日上三竿，部下端来饭菜，其中有一样卤黄豆。关羽马上联想到豆腐，医书上说过石膏性凉，可祛火，不妨试一试。关羽吩咐军士泡豆、煮浆，亲手点石膏，因石膏点轻了，豆腐打得嫩，不能炒。将士们只能用食盐拌着吃，说来也巧，这种豆腐就象一剂良药，将士们吃了它，病慢慢的好了。后来，一些江陵籍的军士把家乡出的皮蛋拌入嫩豆腐，加上佐料，不仅味道鲜美，而且清热解毒，成为一道名菜流传至今。
