I have done the taste test – Not sweet at all, Chalky and a little bitter
I split it with a knife down the line on the backside – Broke into 2 big pieces with some small crumbs
I put one in my mouth for a few seconds (10 or so) and it started to dissolve. Kept its shape but corners were rounding.
I also measured them and they are 6.24mm Flat to point and are 3.17mm wide.
I will try the acid test tomorrow I hope, but until then tell me what you think.
