Hi...after covering your cake with the fondant, (I take it this is when you want it shiny?) take a paper towel, and very lightly apply some crisco to the fondant....Just lightly enough to give it a sheen....Brownie
I had this question once and I got the advice to let a little steam hit it and it worked. It gave it that real shine you see on cakes. PS it begins to shine quickly so dont get too close with the steam. just the mere sense of the steam near it causes the shine.
some 'shimmer' dusts when mixed with clear alcohol (vodka, clear vanilla extract,) add only shine... Especially if you use a white or pearl.. the cheaper the shimmer dust, it'll probably work as a 'shiner' rather than a 'shimmier' (haha).
Here's a cake I did last weekend with Pam on it for shininess. The mother of the groom said that people couldn't stop talking about the logos (edible images), the shininess, or the fact that it was life-size (the armspam was 2.5 feet across). LOL
WowWowzers! So cool. What kind of Pam? Can you use a generic? DO you have to worry about colors running? Does it make the fondant taste wierd? If your fondant doesn't tast wierd already? haha- MIne is yummy. UMmmmm...what else can I ask?
