The reason crumpets are typically packaged in packs of 6 or 9 has more to do with marketing, convenience, and consumer expectations than it does with the number of toaster slots.
Tradition: Crumpets have been sold in packs of 6 or 9 for many years, and this packaging tradition has continued over time. Consumers have become accustomed to this quantity, and it has become the standard in many regions.
Optimal packaging size: Packs of 6 or 9 are considered convenient sizes for consumers. They are large enough to provide a satisfying snack or light meal for individuals or small groups without being excessive. Smaller pack sizes might feel too limited, while larger pack sizes might not be as attractive to the average consumer.
Manufacturing and distribution efficiency: Packaging crumpets in quantities of 6 or 9 likely allows for efficient production and distribution. It may optimize the use of packaging materials and storage space, which can benefit manufacturers and retailers.
Visual appeal: Packets with 6 or 9 crumpets can appear visually balanced and appealing to consumers. This can subconsciously influence purchasing decisions and make the product more attractive on store shelves.
Serving suggestions: Crumpets are often served in pairs or threes, so a pack of 6 or 9 aligns well with this serving tradition.
Ultimately, the choice of 6 or 9 crumpets in a pack is a combination of marketing, convenience, and historical norms. While it may not directly correspond to the number of slots in most toasters, it has become the established and expected packaging for this particular product.
