Which regional US context is noted for having a historical tendency to favor the term 'preserves'?

Answer

Some Southern US contexts

The variation in terminology is emphasized as pronounced in the United States, with specific mention of some Southern US contexts. In these areas, there is often a cultural or historical inclination to use the term 'preserves' when referring to homemade fruit spreads, especially those prepared traditionally using whole fruits or large chunks, which blurs the technical distinction outside of formal commercial standards.
