There are types of food that are nearly only eaten in wintertime or with Christmas etc.
Wouldn't it be nice to maken an inventory of those and then for summer update make Citrus ice or slush puppy, for wintertheme pea soup.
As it is not only food could be seasonal. I'm right now thinking of bikini, winterclothing, rain clothing and so on....
