Okay, I have just put my KA cake in the oven. I am very optimistic that it will turn out quite light!(I'm a bit fanatical at this point about trying to find a 'light' cake! ) I can already tell the difference from this batter (using cake flour) and the other cakes I tried while using AP flour. This batter is MUCH lighter. Figure the end result will be as well. While I was making this cake a couple of questions came up. Before this cake, I had never used cake flour-I wasn't sure if I was supposed to sift it or not. I figured sifting would help with making for a lighter cake, so I did sift it. Also, when a cake calls for two cups sifted flour does that mean to measure out two cups and then sift it or is it two cups AFTER sifting? For this cake I measured after I had sifted. I noticed while I was measuring out my Vanilla that it was a bit cloudy. I had never noticed this before. Anyone know why this would be? Got me wondering if vanilla could go bad. Okay, last question. Is there a real measurable difference between cake flours? I have seen Softsilk mentioned numerous times as being the choice brand. I went to my local grocery store which did not have Softsilk. I'm in Canada, is it even available here? Thanks for putting up with me! I know that my questions give away the fact that I am a VERY novice baker , but I do love baking and have always done it for fun (and stress relief). Thanks again.
