Jan 13, 2017· Batching, or measuring raw ingredients before mixing by weight, volume or both, is another important factor. "Sometimes, weight and proportions change based on sequencing choices made during batching," Ramsburg said. "So mixes should be designed to be batched. Since sequencing affects optimizing the mix design, they should go hand in hand."
