Hi, I hope to get an answer today. I just emptied my bowl of freshly made MMF onto the saran wrap. It was awfully sticky. Should it be a little dryer? Like should I add more sugar? Otherwise, I fear I'll be using a lot of corn starch when I roll it ... but with no real experience with fondant, I don't know how it should be when first made.

not too fast !!!! did you try kneading it first ? it has to be given a good kneading before you can tell if needs more water ot sugar..
if it is still too sticky after a good kneading, then add more sugar...

Since you've already wrapped it, just leave it for 30 minutes to an hour. When you go to work with it, if it's still pretty sticky, add a little more sugar, then roll it out. Corn starch will take the stickiness out pretty quickly, but it also makes it less elastic, so don't use too much!

I would add just a little at a time.... It should be a little little sticky but not much....if it has to much suger it may crack after laying it on your cake....
you could use a powder suger to roll out instead of cornstarch.....until your sure you have the right texture
