Daffodil cake, from Martha Stewart. Edible nasturtiums.
The cake is supposed to have visible layers inside (one white, one yellow.) Mine didn’t. It was also not terribly flavorful, but I guess that’s what I get for baking a glorified angel food cake.
I remembered I had some lemon curd in the freezer, so I spooned some out (it doesn’t freeze solid, it turns out) and had that to accompany the cake. It helped!
