Black Bean Soup Cure For Laryngitis

Re getting your voice back -- After hearing that Japanese opera singers eat black bean soup before performing I tried it for severe laryngitis. I'm a soprano and was singing bass. After trying the black bean soup I was up to alto in one day and back to soprano in two.

Do you have the recipe? I am playing the lead in Cinderella and NEED my voice back pronto. I'm already gargling - but would love to combo the two!!!!! =) Thanks!
