For the Fondant:


2/3 cup corn syrup


2/3 cup hot water


7 cups powdered sugar


6 drops lemon extract


Food coloring








Directions





To make the fondant: Whisk the corn syrup into the hot water until dissolved, then whisk in the powdered sugar until smooth. Stir in lemon extract. Divide into smaller bowls and color with food coloring, adding color until you achieve desired shade.





To make the petit fours, cut the cold cake into small squares, rectangles, and circles using small cookie cutters. Place the cakes on a wire rack over a pan to catch the drippings, inverting them in order to have the golden layer on the bottom. If the fondant has become stiff, just whisk until smooth again. If the fondant is has not become to stiff, proceed to the next step. Either dip the cakes into the fondant and place on the rack to drain or ladle the fondant over the cakes, making sure all sides are coated. Once they are set, they should be coated again. Let dry, then with melted chocolate or colored fondant, pipe thin decorative lines or use silver dragees

Yes, but the liquid colors don't give as strong an end result as paste colors.
