This skill provides the desired bread dough temperature formula to obtain the correct temperatures of the ingredients, room, friction by mixing either by machine or by hand and using water temperature to bring the mixture to the ideal temperature. First determine the ideal dough temperature such as 75 degrees.. you will then need to do the following calculation: 75 X 3(temperature of ingredients, room, mixing friction= 225 ingredients = 71 room = 70 mix by hand= 7 ( average) 225- (71+70+7)=77= the water temperature to bring your dough to the ideal temperature of 75
