Procedure
Combine phase A to main vessel with agitation. Sprinkle phase B into phase A while mixing. Allow to hydrate. Increase agitation as batch thickens. Mix until uniform. Premix phase C and add to main vessel with mixing. Begin heating batch to 80-85°C. In separate vessel, combine phase D with mixing. Heat to 80-85°C. When vessels have reached 80-85°C, add phase D to main vessel. Mix until uniform. Then begin cooling. Premix phase E. When main vessel reaches 70°C, add phase E with mixing. Mix until emulsified. Then cool to 40°C. When batch has cooled to 40°C, add phase F ingredients individually with mixing between additions. Mix until batch has cooled to room temperature.
