I was amazed when I started meeting professional bakers through the
Bread Bakers Guild of America that they all were so willing to
give away their formulas.
Partially it's just because "bread people are good people." :-) But
also, they knew that their own skill and personal touch made a huge
difference in how the product comes out.
So they knew that even if they gave away the recipe, they weren't
really putting their businesses at risk.
In light of this, I now find it amusing when people resist sharing recipes.
