I just want to add to the Toba Love Fest -- I use it all the time and love it. It freezes really
well. I iced and decorated with RI and then sealed them in a Ziploc. Once frozen, placed them stacked in a Tupperware container. They came out just fine and no one could tell they had been frozen!
I make what I call "Map cookies" for my DH. After rolling out the dough a couple of times, I take all the scraps, moosh 'em, and re-roll. I use a knife and cut them into semi rectangals. I ice with all the leftover glace mixed-up, dry and then freeze -- that way I can give him a treat from time to time. I call them maps because he wanted to know why I did cookies shaped like Arizona and Wyoming???
