One day in advance, make fondant topper.
Tint fondant following color formulas above. Use 9 in. fondant roller with pink guide rings to roll out white and tinted fondant, separately, 1/16 in. thick. Use round cut-outs to cut one shape each: smooth side “A” size in yellow, scalloped side “B” size in white, smooth side “D” size in orange. Use smooth side of blossom cut-out “E” to cut shape in red. Use damp brush to attach centered shapes from largest to smallest. Let dry overnight on cornstarch dusted surface.
