I am a big fan of yeast. Yeast are my friends. They work hard for me. I like yeast so much I keep a few in a tub in the back of my refrigerator. There they happily coexist with their good friends the lactobacilli, all chomping away in froth of water and wheat flour.
Cats and dogs make me sneeze. I am unable to keep parakeets happy. But even if they are mere fungi, my yeast make great pets. I just have to feed them once a week, or leave them with friends when I go on vacation.
