Thanks to all those of you who offered advice on my pudding and egg white dilemma last week. Apologies to those whose advice I subsequently ignored :)
I actually went ahead with the crazy winter pavlova idea, and it actually turned out reasonably nice. (At least, I thought it did. And other people said they liked it, though they may have just been polite.) I had some leftovers the day after, and they were definitely at the "leftover" stage, a little soft/soggy for meringue, but not to the point of inedibility. But the pavlova coped fine with being assembled around 6ish and eaten around 9ish.
deborahw37 requested a picture, but I'll put it behind a cut in case the rest of you have had quite enough of my culinary excess this month.
