Okay, Laurel's Kitchen Bread Book (the basic whole wheat recipe) says to allow 2-1/2 hours for first proof at 70 degrees (my thermostat read 71) . I can't even get to 2 hours before it's doubled and the poke test fills in, but VERY slowly. A few minutes one way or another is fine, but nearly one hour difference? Am I mis-reading the fingerpoke test? Do I have fantastic yeast and flour?
