What characteristic reportedly defined the international Mars bar compared to the US Milky Way recipe when Forrest Mars sweetened it for the British market?

Answer

It was sweeter due to the addition of more sugar to satisfy British preference.

The divergence between the US Milky Way and the international Mars bar highlights a deliberate act of brand segmentation based on perceived regional palates. When Forrest Mars developed the international version, he intentionally added more sugar to the recipe compared to the US standard. This modification was made specifically to satisfy the British preference, which favored sweeter confections. This adjustment resulted in the international Mars bar—which otherwise uses the US Milky Way's components of chocolate, caramel, and nougat—being noticeably sweeter than its American counterpart.
