Can someone please share their "technique" for grating carrots using the UM? I managed to get them grated for the carrot cake cups yesterday, but I'm sure that no one would want to purchase the mandoline because of my flawless technique! Do you "stand them up" and poke them with the tines of the holder, or lay them down sideways? I kept having big chunks of ungrated carrot slip out of the food holder. I was using whole large carrots, which I peeled and then cut into about 4" pieces. DETAILED instructions would be appreciated! Thanks!
