Where is the excerpt? If you could let me see it I could help you.
In the excerpt, the word "pungent" refers to the pickles' aroma.
Pungent is a word to describe a very strong smell, very sharp and biting. So when Untermeyer used the word pungent to refer to the pickles, he was talking about their aroma, which is a fancy way to say smell.
