I am about to make some bread later today, I made a Biga 1 1/4 cups  flour 1 cup water & 1/4 tsp Instant yeast. question I have is when I put the Biga mix in my bowl and the remaining 3 cup flour, how much more yeast do I have to add. this bread recipe without the biga calls for 2 1/4 tsp yeast, 4 cups flour, & 1 1/3 cups water & one egg. sugar & salt.
