Should you be attempting to garnish an item which has already dried (chocolate ganache) or is quite dry inherently (sugar cookies), try very lightly moistening the food surface. A perfect solution is to spray a small amount of Evian water from a canister over the items. The mist filters down and leaves just enough moisture on your items to insure they adhere. A very interesting application is also using both the silver and gold together to sprinkle on a dish. It is beautiful on basmati rice and desserts.Gold will not lose its shine up to 325º and can be frozen!
