For $250 I would want it to perform for me!
. As for knives I am in love w/ my Wusthof & it too cuts like butter & I bought it at TJ Maxx for about $20.
As for the dishtowel method I have had luck & no luck. Think the no luck was actually the cake itself--it was a total nightmare anyway. Heard about the nail, but not tried it yet. My instructor told me to use it on 10" or above & I've not baked any that large yet.
I too am interested in how you use the towel method on cupcakes--I have the darndest time w/ cupcakes. Do you just pat them individually?
