A modern Jewish novel

[Dilbertian]

I read a novel, American, probably late 20th century, possible 21st century, about a group of women in a Jewish community. Definitely not in New York or Hassidic. Modern Orthodox, I think. There was a character, either a convert or a Jewish woman who became more orthodox after marrying into the community, who kept a treif spoon buried in her garage freezer so that she could secretly eat shrimps from time to time.

Does this ring any bells?

I think its The ladies Auxiliry by Tova Mirvis. although i don't recall the shrimp spoon.

Sounds familiar. It’s probably on my bookshelves somewhere. Thanks.
