In regards to the carrot cake method used above -- I've had great luck with the oil/egg emulsion. The cake stays moist for days and doesn't feel greasy at all. I whip the hell out of my eggs (for over 10 minutes) and then stream in my oil and whip for another 5- 8 minutes, dump in sugar, whip for another 2-5 minutes and then fold in my dry ings. and carrots separately. But speaking of fruit purees -- are there any out there that don't impart too much fruit flavor? I know it might seem contradictory, but I'm looking at making some of my more neutral cakes (yellow, white, etc.) a bit more moist without taking on an apple/pear/banana/whatever flavor or color. Or has anyone found a nice ratio of fat to puree that they have had good results with? Thanks for the responses (even though I am a bit off-topic.)
