I'm looking for a children's book that I read as a kid. However, I can
only remember vague details about the book (really, just one part of
it, and the details aren't very precise).

The book features a village ridding themselves of flies (or wasps or
other bugs) by making a giant piece of dough (or bread or other
pastry-type substance) with jelly or something sweet like that. I
believe the bugs were attracted to the sweetness and then got stuck in
the dough.

Name, Author and ISBN number would be perfect.

Thanks!

This sounds like The Giant Jam Sandwich, by John Vernon Lord.  ISBN
0395442370.  Amazon.com link at: http://tinyurl.com/d6xyv

Hope this helps you!

That looks like it! Thanks so much!
