In a separate vessel, combine D and start heating with mixing to 50°C.  Add E to D. When DE is at 50°C, add F and stop heating. When fully dissolved, add G to DEF. When fully dispersed, with mixing but without aeration, add DEFG to ABC. When the batch is fully-formed, switch to sweep mixing. Premix H. Add H to batch. When batch is homogenous, add J and replace any water lost during processing.
