Before applying gold leaf, make sure your cocktail is properly chilled and garnished at your special occasions. You can use any cocktail that you like, but clear drinks like martinis or champagne cocktails work best. This is because the gold leaf will be more visible. 2. Cut a small piece of gold leaf using clean scissors. The size you cut should be slightly larger than the surface area you want to cover. 3. Gently place the gold leaf on the surface of the cocktail (or garnish) you want to cover. Use a small brush or your fingers to press the gold leaf onto whatever surface you’re adorning.  4. If you want to add more sparkle, repeat the process until you have achieved your desired look. 5. Once the gold leaf is applied, serve your cocktail immediately and enjoy the shimmering and luxurious effect it adds to your drink.
