Wow.  Gosh, the cake was actually better today (the day after it was made).  The lemon has soaked through the sponge and the slight (not unpleasant) egginess of yesterday has vanished, replaced with a mellow lemony taste and a subtle crunch where the syrup has hardened to a sort of glaze.

And I still have a little left.  And more at home!  Woo!
