When I purchase raisins in the US, it is not uncommon that some of the raisins have bits of stem still attached to them. However, when I purchase breakfast cereals with raisins included, I seem to never encounter stems. Clearly there is a difference in how the raisins are processed. But what is that difference?
What about the processing for breakfast cereals make stems so uncommon, and why is that same process not considered for raisins sold alone? Is it the cost of some extra or different processing, or are perhaps all these raisins processed the same but then dividing into low- and high-confidence-no-stems pools, the latter used in breakfast cereals?
