My current favorite YouTuber, emmymadeinjapan, gamely tries a lot of very challenging, even impossible-looking recipes (when she's not cooking jailhouse meals or eating giant crunchy bugs). The jiggly cheesecake has just caught on in Vancouver, to the point where my son-in-law had to line up for a taste. Verdict: OK, but not great.
I think the best part of it is the jiggle itself, which is most in evidence when the cheesecake is just out of the oven. It looks more like a souffle to me, more eggy than a normal cheesecake, and I'm not sure about the crust. But I love the moment when Emmy tastes anything: rhapsodic when it's great, ruminative when it's in the middle, and dismayed when it's not good at all or just lets her down in some way. And her standards are high, as it's obvious she has had chef training: handy with a knife, a strainer, or a jigglypuff cheesecake.
But what I like best is that she will try making something again and again until she gets it right. And this time. . . she gets it right.
Am I going to make this? I can't even do a normal cheesecake, so it's doubtful I could master this. But I might buy one, unless I have to line up for it.
