Verdict: not too bad. I like the fact that it is not overly sweet. It seems a little denser than many similar items, but that's not a bad thing necessarily. I hope it is as good when it has cooled completely.
It appears my oven does indeed function at the temperature advertised, always a plus in these things. There you go, Joy - you can still adequately prepare a box of X. Just like falling off a bike - these sorts of skills only become rusty, they never truly disappear. Well, and gravity helps too - but I digress.
Oooh, maybe tomorrow I'll be really brave and scramble one of the remaining eggs. I don't know though, that might be moving a little too fast...
[you know, it's a damn good thing I amuse myself as much as I do. I feel sorry for the rest of you poor folks...]
A thousand blessings on the heads of rwx who suggested the mix, and faintheart who was kind enough to procure it.
