Finding high protein flour in the US is easy. Wal-Mart for starters
usually carries King Arthur but any brand (Pilsbury, Gold Medal, etc)
make bread or "better for bread" types (which means high
protein). Actually any supermarket has several brands and
types. All-purpose flour is lower protein. Bread flour is higher
protein. I usually try and get unbleached. The instant yeast is
also available everywhere, usually in bricks that are $3-5 and, if
frozen, last forever.
Start with Peter Reinhart's Bread Baker's Apprentice and Rose Levy
Beranbaum's The Bread Bible. Both mention specific yeasts so you'll
get the right one! They'll spell it all out!!!!!!!!!!
