RE: Peppermint Stick Ice Cream
Just a thought, but I think if you want it year around, I think you can get it from the major producers. The key is to speak loudly and carry a big peppermint stick.
Speaking loudly: Anyone can create a blog on the web for free these days, a few people doing this dedicated entirely to this subject, mentioning their favorite brands that do it part time, may awaken these brands to the fact people like this flavor year around.
Carrying the big peppermint stick: If the brands do not respond, encourage the readers of your blog to pester these brands until they do so. This would include boycotting the brand until they came to their senses.
This approach even benefits the producers. They know what people want and they can save a lot of money by firing their very expensive consultants that do not know anything about what the consumer wants.
