What I've seen is that most people have actually eaten around 30-50 of the items on the list, not 20. Like any good overachiever, I come in at 91/100 - only good for a lowly A- that would earn the ire of my Asian parents. (Just kidding. We're grading on a curve here, right?)
Here's the list - post how you did in the comments!
11. Black Pudding
12. Black Truffle (I have, however, been obsessed lately with white truffle salt.)
26. Crickets (I'm adventurous, but I draw the line at insects. I don't even want to look at them, much less put them into my mouth.)
28. Dandelion Wine
63. Nettle Tea
100. Zucchini Flowers
