I take a sacrificial slice to inspect the cake. It's slightly denser at the bottom -- perhaps inadequate folding -- or too low of a temperature?
In the end, the 2nd attempt was slightly better, but still nowhere near the 2.65" in height I deduced from the photo in RHC. I decided to carry on with the cake as I had invited my running friends over for cake and running, so I needed to serve something!
See how short it is...
This is one of the most refreshing cakes I have tasted. The cool wetness of the cake demands that it be served on a hot summer's evening -- but I too enjoyed it in my balmy winter temperatures of 0C -- really it was so nice to go running in temperatures above -20C! However, the texture was less airy than it could have been with the added height. The carmel milkiness is divine and definitely cake I must learn to master.
