You will need granulated sugar, water, food colourings and a heart shaped cutter ( or any shaped cutter).
Firstly add a little water to your sugar, not too much and not too little, it should look a little like crushed snow!! You don't want it to be too wet because it will no longer look grainy once it has dried, but you want it wet enough to stick together once you have pushed it through the mould.
Separate the water and sugar mixture into a few different containers, I used paper cases. Add the food colouring of your choice a drop at a time, depending on how light / dark you want the sugar cubes to
Fill your mould with the sugar mixture.
Push down the sugar with your fingers. You need to do this otherwise once you push it through the mould there may be a gap in the middle and it will collapse .
Leave them for a few minutes to dry a little and then carefully push them through.
It may take a couple of tries as it is quite a fiddley job. Some of mine came out too wet, some were not wet enough and some were just right, so keep trying!!
They look very pretty in a jar on the shelf for when you have your girlfriends over. Altough I am not sure if they will colour your tea!!
