Another point to consider is the popularity of different apple varieties over the last few decades. Red Delicious was the top choice in the 1950’s and 1960’s. If your character is living in those years, they probably would eat a Red or Golden Delicious apple. Because the Delicious flesh is often mealy or mushy, the Gala became a favorite for it’s crisper and juicier texture. After the Galas, Fuji, with its dense, crisp, and sweetly tart taste was the biggest seller. Next came the Honey Crisp with a sweeter taste that has been my favorite. Today new varieties are available such as Jazz and Envy, although harder to find, Envy is equally as good as the Honey Crisp.
I consider my characters’ ages and personalities to pick a type of apple for them. Hada and Lev in Hada’s Fog, because they are in their 70’s, would eat Red or Golden Delicious and then complain that the ones they bought were mushy, but the couple resists change to a crisper apple. Jill, in Norman in the Painting, would prefer Honey Crisp and Reggie, the antagonist, would buy Jazz apples. Arctarius, the mysterious character, might choose a Fuji.
Apples may not enter the story at all, but they are an addition that could enhance it.
What kind of apple does your character prefer?
