Pinwheel Cookies (big puffy chocolate covered marshmallows with chocolate cookie bases) are a pretty good seasonal treat. Though I've seen them in the summer sometimes recently, but the chocolate coating isn't the same as in the winter.
A new one from this year is Woodstock Inn's Wassail Ale. I've gotten it quite a few times since I first saw it in November. I'll be looking forward to that again next year.
I also really look forward to asparagus season in the late spring to early summer. I can't stand the frozen stalks, and there's only about a month or so when the asparagus is good around here.
I used to love those frosted christmas tree cakes when I was a kid. My parents bought some of them this year when we went to visit them, and I was scared to eat one. They are pretty, but don't look like food to me anymore.
Lloyd: When I met Mary, I got that old fashioned romantic feeling, where I'd do anything to bone her. Harry: That's a special feeling.
I second the Edy's Thin Mint ice cream. It's very good. I also like the Thin Mint Blizzard at Dairy Queen. I think that was last year's April Blizzard of the Month. (I find I like it better than the Mint Oreo Blizzard (March) or the Yule Flip Peppermint Chip Blizzard (December). Yes, I love mint ice cream.)
I also like the cranberry-flavored Sierra Mist they sell for the winter holidays.
In Sydney they like to honk a bit but in the rest of the country not so much in my experience. When you do get a honk it's often the more protracted HOOOOOOONNNK which is used to register your disgust at particularly moronic or selfish driving.
