hi, all—a newbie here. love the site already!
cutting to the chase: i’m helping out my little sis last-minute and baking her wedding cake. i’m in d.c.; she’s in denver (so questions about transporting TK). right now, though, i need help translating her recipe into a three-tier three-inch-high layers cake. it will be 6-, 9- and 12-inch tiers each 3 inches deep. i have a fisher-paykel aero oven (convection-like). but i’m finding that the deeper layers, of course, bake differently. and i’ve been through my inherited copy of the cake bible—and i’m sure it’s my failing—but i’m not really able to translate the recalculations for butter or sponge cake into carrot when increasing a recipe to wedding-cake-size. this isn’t a sponge or a butter cake, technically. and of course it’s got a lot of liquid:
2 c flour/1 tsp each baking soda and powder/ 1/4 tsp salt/ 2 tsp cinnamon
3 eggs/ 2 tsp vanilla/ 1.5 c sugar/ 1/2 c brown sugar/ 1/4 c milk, then 1 c oil
2.5 c carrots/ 2 c shredded coconut/ 1 c crushed pineapple/ 1 c yellow raisins/ 1.5 c chopped pecans
for the first shot, i just quadrupled the recipe (which seemed to be enough for the 9- and 12-inch layers). no other adjustments. my 12-inch layer took quite a while to bake, and it seems the very center is a bit underdone.
i’ve been baking a while but am just starting to get serious about it and work to understand the scientific side. and i’ve never baked anything on this scale before. and i have little time—i need to either ship the cake in a week or carry it on a plane dec. 28. i’m now leaning toward freezing it, repacking in pans (plan B is to rebake in denver if necessary, though that’s plan B because i’d have a lot of trial and error due to high altitude adaptations) and assembling and decorating out there (making white chocoate cream cheese frosting out there as well). does that seem safest (despite rose’s brother’s wedding cake catastrophe story? —i’m flying nonstop to denver. i thought i’d pack it in its own suitcase, as it’s probably too heavy to carry aboard. also, the cargo hold will clearly keep it more than cold enough.
any and all advice is most appreciated! i know i can do this for her with the proper guidance and effort. hard work and long hours are not a problem.
