Larger  pieces  of  dough  should  be  proofed  at  a  lower 
temperature while smaller pieces are proofed at a higher 
temperature. 

Basic yeast dough should be at room temperature when it 
is placed in the proofer. Placing retarded dough (directly 
from the walk-in or refrigerator) into the proofer cabinet 
will often result in excessive build up of condensation on 
the  surface  of  the  dough.  This  may  lead  to  crust 
imperfections  (spotting  and  streaking)  and  blistering.  In 
severe cases this may often result in total collapse of the 
baked product after removal from the oven. 

It  is  important  to  stage  your  retarded  product  into  the 
proofer  to  avoid  "overproofing".  For  optimal  results  the 
product  must  be  baked  immediately  after  the  proofing 
process. 

The  majority  of  yeast-raised  products  can  be  proofed 
successfully between 90° - HOT and 70% - 75% relative 
humidity.  The  quality  of  your  final  product  will  depend 
on  the  initial  product  quality  and  handling  from  the 
freezer to the oven. 

Proofing Bagels 

The proofing process allows the bagels to warm up and to 
expand slightly before they are boiled. Bagels which are 
not proofed sufficiently, may not rise to the surface when 
they are boiled. However, overproofed bagels will tend to 
collapse  after  boiling  and  before  they  are  placed  in  the 
oven. 

Optimum  temperatures  and  times  will  vary  for  various 
bagel formulations. All bagels should be proofed at a low 
relative humidity (65% - 75% R.H.). 

Bagels which have been held overnight in a retarder or for 
a  short  time  in  a  freezer  are  usually  allowed  to  proof  at 
lower  temperatures  (86°  -  90°F)  than  bagels  processed 
without  interruption.  Continuously  produced  bagels  are 
generally proofed at 104°-110°F.
