A Tale of Two Cakes... and Curd

It was the best of times, it was the worst of times. But that is a gross exaggeration.
In the picture above, you can see two slices of angel food cake and a lovely dollop of homemade lemon curd. The slices are from different recipes for cake. One cake, I made with egg whites and the other I used meringue powder. Why bake two cakes, you ask?
I couldn't see making an entire tube angel food cake, so I halved the traditional recipe and baked it in a loaf pan. The problem was that the pan I grabbed was an insulated loaf pan. Big mistake. The cake needed about 25% more time in the oven than a non-insulated pan would've required and the cake was still somewhat underdone. It tasted ok, but you can tell an angel food cake has too much moisture if it collapses a bit when you're cooling it. And, yes, I was cooling it upside down!
I had already made the lemon curd and started to worry that the cake wouldn't be a suitable accompaniment for it. I didn't have enough eggs to make another cake, but I did have meringue powder. I've never used meringue powder to make an angelfood cake before, but it turned out very well. The biggest difference between it an a typical angel food cake is that it didn't rise as much - the top of the loaf was much flatter. My tasters prefered the meringue powder cake to the egg one, but I know it already had the advantage because it wasn't underdone.
The lemon curd, however, was problem free and delicious.
