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.
I went to Peanut Butter & Co. back in June and I had the White Chocolate Wonderful sandwich. Hell to the yes, that is amazing. FWIW, my friend who showed me the place couldn't stop raving about the Mighty Maple. We need to go there again, ASAP.
