It is impossible for me to pick just one, I have passionately loved Chocolate for many years. Off the top of my head, I can think of a few experiences: A Tolberone bar when I was a child on vacation with my family in Chicago's "Palmer House" or Denver's "Brown Palace" Hotel (I have the memory, but am unsure of the location), Makinack Island Fudge in Michigan, and when I discovered that right here in "Low-Culture" Fort Wayne we had marvelous "DeBrand Chocolates" ( http://www.debrand.com/ ), or when I discovered a British brand of truffles I have never heard of (Charbonnel et Walker Chocolatier) in the basement of Marshall-Field's (what a wonderful discovery!)!
There is one more memory I would like to add: I have been a lover of the culinary arts for many years as well (My late father was my family's gourmet cook at night and a doctor by day). When I was around 11 years old, my father told me about when he was my age in Germany where he was born. He said that it was normal in Germany for young men and women in their teens and pre-teens to stop at the local bar on the way home from school and get a beer. He also told me that public drunkenness was socially shameful, so few people would ever get drunk. Ever since then (and when I was younger as well), my father would teach me about wine and beer and the culinary arts. At 19, I began collecting (very modestly) wine. As I grew-up, my palate became more sensitive and "educated." What does this have to do with chocolate? Well, I studied food, wine, Cognacs, Single-Malt Scotch and Bourbons, and beer! One day, not too long ago, I discovered I favored rich stout beers. Finally, my palate was developed enough to realize why. My "EUREKA" moment was when I realized I loved stout-beers because of the flavors of coffee and CHOCOLATE! To this very moment, I love stouts because of the chocolate flavors they contain. Often, I love Whiskeys for the same reasons, the chocolates, smokes, woods, and caramel-flavors they contain. And again, this is why I love fortified wines (Portos and Madeiras) as well!!!
My favorite chocolate is:
Very Difficult, pure chocolate bars (of Milk and Dark), "Connoisseur Collection" or fruit-cordials from Debrand, or a simple Milk Chocolate Bunny from DeBrand (I am only 29 years old!).
