Hequ sour porridge

Hequ sour porridge is a special food of Hequ generation. According to legend, it can stimulate the appetite, strengthen the spleen, protect the skin and beautify the face, which is wonderful. Legend has it that the Li Zicheng Uprising Army passed by Beijing, and the local people were all happy. Every household soaked rice to prepare meals for the soldiers of the army. Unexpectedly, due to changes in the situation, the army temporarily changed its route and bypassed it, but the people soaked too much rice, which they could not finish for a while, and it became sour after a long time. People were reluctant to throw it away, so they cooked porridge with sour rice. Unexpectedly, it was found that the porridge cooked with sour rice did not affect its edible value. Later, people deliberately made porridge with sour rice.
