I have a question about Salinger’s “Down at the Dinghy”
Pickles, particularly the small kind are usually served in delicatessens alongside sandwiches with meats like Pastrami and Corned Beef. Like a lot of people, I think of deli foods with cured meats as being a sort of jewish-american cuisine.
Probably because I am from New York where a lot delis were Jewish owned (idk of this is still true today, but like pizzerias and Italians it’s a sort of an undying association). Salinger, who was brought up in New York when these ethic cuisine associations were a lot more true might have made a similar association.
So really, what I’d like to know is if the child, Lionel, is said to love pickles as some kind of allusion to his Jewish heritage or if that’s just what Salinger thought children liked to eat?

I can elaborate with excerpts but I know Salinger and Nine Stories are pretty commonly read on /lit/
