I tried the impossible burger last week, from a local chain called Super Deluxe which aims to reproduce the basic burgers from In-n-out (and mostly does quite a good job). I could tell it wasn't meat, but it was a near thing. The texture was just slightly too soft. Otherwise it wasn't half bad.

What did surprise me was the aftertaste. I get a fairly strong aftertaste when I eat chicken, for example, but not beef. I'm certain not everyone experiences that, and I've never had an explanation. Interestingly, after the impossible burger I got the same strong aftertaste. That may be a clue I can use to identify what causes it to happen for me.

I'd have another one, but I do prefer the beef version a little, and I don't often go to Super Deluxe so when I do it's going to be the real deal.
