I wonder where the shape of pretzels originated.
My guesses:
- The holes make it easy to put them on a stick or rope and store them in a place (under the roof?) where mice would not get it.
- Originally the pretzel was a long thin stick, but it was impractical to transport. The pretzel shape provided stability to carry it around. It could be broken into smaller stick-like pieces and eaten.
- It resembles some symbol.
- Just for fun, because the kids liked it.
