The villagers decide to build a gigantic jam sandwich to trap the pesky insects.
Usually this consisted of jam sandwiches, or "jeely pieces" as they were called locally.
Apparently the poachers place food such as jam sandwiches on the road to attract deer.
This colour scheme is reminiscent of jam sandwiched between two slices of white bread, hence the name.
Today, jam sandwiches are mainly consumed by children.
