Per Anne, previously in this thread:
“Another possibility is to syrup your butter cakes. Again, I’m not a fan, but many are, and, if the weight of the sugar in the syrup is equal to the weight of the sugar in the cake, it will moisten, but not sweeten, the cake. Several of Rose’s recipes call for syrups—the lemon poppyseed bundt cake from RHC comes immediately to mind—but you can syrup any butter cake. You can also flavor the syrup with liquers and such if you want to….
Of rose’s cakes, I’ve found the Golden Luxury Butter Cake to be the moistest and fluffiest. It uses white chocolate for part of the sugar (and fat), as well as all egg yolks. It’s my favorite yellow cake. I think that buttermilk is supposed to produce a very moist cake, so you might want to try the TCB buttermilk country cake and see if you like it. It also uses all yolks, but you can sub 2 eggs for 4 yolks if you prefer (I like all yolks, myself)—Rose does this when she uses this cake as the base for the RHC spice cake.”
I was excited to see this thread about keeping cakes moist, as I am making the second of two wedding cakes for friends this summer. (My first wedding cake was just 2 weeks ago, and it went very well, thanks to members of this forum!) The next wedding is in 2 weeks and I would like to assemble the cakes 2 days ahead so. i can attend a family tea for the bride the day before the wedding. I have tried syruping before, but it is a mystery to me. I know Rose has a chart in TCB that I can use as a guide, but how do I gauge how much is actually enough for my cake? I did try to syrup a cake once, but it definitely was not enough, or I didn’t give it enough time to distribute throughout the cake. (I was afraid it would turn to mush.) Does anyone have any tips on this?
I was also happy to see Anne’s reference to Golden Luxury, and mention of subbing whole eggs, as this is the cake I was planning to use. I’m planning on subbing 2 eggs for 4 of the 6 yolks, just because I would like a paler yellow cake (& maybe subbing part of the milk for buttermilk for moistness?) Will it still stand up to the filling I’m planning to use, which is a white choc frosting bumped up with raspberry puree and sprinkled with red raspberries inside - a 3-tier cake. (Thanks to Prettycake for answering my questions yesterday about the longevity of fresh raspberries in the filling- she made a beauty of a Red Raspberry Cake that’s displayed in Show&Tell;.).
Any helpful comments, ideas or tips about any of the above would be appreciated. Thanks!
