Piped flowers: nails, paper and the transfer

Three ways to work, and when to use each

Direct on the cake: fastest, no transfer risk, but you cannot turn the flower independently of your own hand, so petals come out uneven. On a flower nail: the work rotates under a stationary bag, which is why 104 roses and violets are piped on nails. On a square of baking paper on a turntable: best for small flowers in quantity, because the paper can be moved out of the way and the flower slid off later without being touched.

The petal tip is a blade, not a nozzle

Petal tips - 101, 102, 103, 104, 105, 124 - have a wide thin opening that shapes a ribbon, not a rope. The wide end must touch the surface and the narrow end must lift: at 30 degrees for a primrose petal, 45 for a rose petal, 15 for a flat daisy petal. If the whole blade lies flat, you piped a wing. If the whole blade is lifted, you piped a blade of grass.

Freezing piped flowers

Buttercream flowers freeze well and this is the single biggest time-saver in flower work. Pipe a tray of roses on paper squares, crust them 24 hours at 18 C, then freeze on the tray for two hours, bag them hard in a rigid container and keep at -18 C for up to two weeks. Thaw at room temperature for 40 minutes, in the bag, still on the paper. Never thaw in the fridge: condensation beads on the petals and the edges go translucent.

Storage and transport on the cake

Once transferred, flowers are as strong as their crust. A rose crusted 24 hours survives a two-hour journey at 18 C in a box with a 40 mm collar; a flower moved at six hours does not. Where flowers are the tallest element, box the cake with a collar rather than a lid, and place the box on the floor of the car rather than a seat: the floor has less vertical movement.

Wire-free is a choice, not a limitation

Wired flowers let you build sprays that hold a shape, but they introduce a food-safety step - wires must be taped or a posy pot used - and they cannot be eaten. Every flower on this site is wire-free: piped buttercream in the same icing as the cake, which means the decoration can be cut and eaten with the slice, and there is no non-edible component to warn a guest about.

Which flower to pipe on what

Flower	Working surface	Tip	Setting
Rose 104	40 mm nail + paper square	104	24 h at 18 C
Crescent rose	Direct on cake	124	24 h, do not chill over 20 min
Primrose	Direct or nail	104 + 3 for the eye	20 h
Violet	Nail + paper square	105 + 1 for the throat	36 h
Hydrangea cluster	Direct on cake	109	12 h
Poinsettia	Paper square, 110 mm	352 + 3 for the beads	48 h

Flower bench rules

Cut paper squares twenty at a time so a finished flower is never waiting for one.
Chill a transferred flower for 20 minutes, never longer: butter fats separate and edges go greasy.
Check a flower at eye level, side-on, not from above.
Keep flowers out of the fridge once crusted; the fridge is for setting, not storing.
Have a box collar 40 mm taller than the tallest flower before you start piping.
