Today, I am trying my hand at making bread and growing a yeast culture. I will post randomly in the future about ingredient parameters and results.
Culture: 1 packet expired Fleischmann's active dry yeast, half cup flour, half cup water, 1 tsp sugar. Sitting on top of fileserver.
Proof: 3 cups flour, 4 heaping kitchen spoons of culture, 1.5 tsp salt, 1.5+epsilon cups water, mixed to watery dough consistency. Sitting atop desktop over CD drive. After extracting from culture, about 1.25 cups remaining.
