I love this thread... I waited 10 years to buy my KA, and got a 5Q for only $199! (just had to say it) While I know it's possible to do a lot of things with a hand mixer, the KA saves you a great amount of time. I am also a self-taught baker, who's learned through trial and error. I have my favorite recipes which have yet to fail me. I only use Cake Flour, SoftasSilk from Pillsbury. My cakes are light and fluffy all the time. I tried with AP just to check if it was all in my head, but the difference is obvious. I like to use AP for some chocolate cakes. Questions: 1-My first set of pans were all 2". But then I figured I'd try the 3" to save some time and effort. Both sizes, 8" and 5" collapse in the center, and on the few occasions in which they haven't, they're condensed. I am making a few wedding cakes in the upcomming months and am debating whether or not to buy my missing pans 3" high. What say you? 2-If going 3" high, what's the biggest I should go with 3"? I'll be making 16" bases. 3 - As for baking temperatures, I normally bake at 350 and have no problems. For pans larger than 12", would you recommend I lower to 325 instead? 4 - And the biggest one: How many cake pans can I bake at the same time in my oven??? As I mentioned, I have pans 4-12 2"high, meaning I have to bake two in order to get my wedding tiers. In fear of spoiling the batter, i've refrained from baking on multiple racks. I bake mine in the middle of the oven; whatever fits on the rack without being to tight. It will take me about 7 hours to bake a 6,9,12,15! NYCMike- for the aluminum pans, you can go to Broadway Panhandler - 477 Broome St. Their prices are very good...Don't buy them at NYC Cake Dist...On the other hand, if you don't mind ordering on-line, you can visit www.bakedeco.com. They're in Brooklyn.
