Eu tentei fazer pão uma vez com levedura de cerveja que sobrou. Foi o pão mais denso que já provei. Panificação não recomendada.
Você poderia tentar fazer vegemite.
How to make Vegemite.
Brewer's yeast is a good source of vitamin B, but live yeast tastes boring, it is poorly digested. Inactivated yeast lacks the disadvantages, but is still bland. The inventor of vegemite solved this problem using autolysis: a process where the yeast's own enzymes break it down.
Spent brewer's yeast is sieved to get rid of hop resins, and washed to remove bitter tastes. Then it is suspended in water at a temperature greater than 37 C with no nutrients: the yeast cells die, and vitamins and minerals leach out. Then the proteolytic (protein-splitting) enzymes take over, breaking the yeast proteins down into smaller water-soluble fragments, which also leach out. The yeast cell membrane is unruptured during this time, and can be removed by centrifuging. The clear light brown liquid is then concentrated under a vacuum to a thick paste (the vacuum helps preserve flavours and vitamin B1, thiamine). It is seasoned with salt, and a small proportion of celery and onion extracts to increase the palatability.
