WARNING: Please be careful – make sure you use gloves and a heatproof mat.

You will need


  • Clear isomalt (you can buy coloured if you prefer not to colour your own)
  • Food colouring of your choice (neon pink was used)


  • Champagne flute or wine glass
  • Heatproof silicone mat
  • Gloves
  • Clothes pegs
  • Pan or microwaveable bowl


Lay out your silicone mat and get your gloves on. Melt the isomalt in the pan (you can do this in the microwave, 30 seconds at a time). When you see the bubbles forming on top, it's ready.
Add the pink food colouring to your isomalt (still on the heat) and once you get the colour you like, leave to sit for a few seconds until there are no more bubbles (neon pink was used for the photos as it shows up better, but the final sail was made using rose which gives a more opaque look).
Start to pour the isomalt onto the mat into a circle.
Place over the top of the wine glass to give it a curve. You can pull the sides in or twist the mat to create flow.
When you’re happy, peg the corners so that you get the shape that you like. You must move quickly though so it doesn’t set or break!
Once set, peel it carefully off the mat – do this before removing the pegs as the sudden movement on the mat when you take the pegs off can cause it to break.
This photo shows another method, which is to set the mat up first and pour the isomalt carefully on whilst it is already in place.
You'll get a similar effect but much longer drips doing it this way.
