Ahhh!! I've finally got it! After over a year of trying a BAZILLION different techniques, I've finally figured out how to make modeling chocolate PERFECT, every time! (A HUGE shout of to the fabulous Liz Marek, of Artisan Cake Company, who also has a channel here on YouTube that you REALLY need to check out, btw.) I've basically just added a an extra step to the fabulous technique she uses, and voila! Tiny little chunks in my chocolate are a thing of the past! Yeeeeeehawwwww!
