  1. 1

    Preheat your oven to 93.3 degrees C. Pour sugar into a measuring cup, filling to the 2-cup mark.

  2. 2

    Scoop and measure out 2 tbsp of sugar from the measuring cup. Add this smaller amount into a plastic zip-lock baggie.

  3. 3

    Measure out 4 tsp of liquid food colouring into a cup.

  4. 4

    Use the dropper to add one drop of food colouring into the baggie of sugar, zip the baggie closed.

  5. 5

    Shake the bag and carefully work the food colouring through the sugar by hand, kneading the baggie. Add one drop of food colouring to the baggie at a time to achieve the darkness you desire. The sugar should have a moistened consistency by the time you are finished.

  6. 6

    Scoop out the coloured sugar and place into the ice cube trays, packing tightly.

  7. 7

    Use the butter knife to level the top of the sugar in the trays.

  8. 8

    Place a piece of cardboard over the top of the ice cube tray and flip over to release the sugar cubes onto the cardboard. Tap the bottom of the tray gently if needed.

  9. 9

    Place your coloured sugar cubes on the non-stick baking tray and bake in the oven for five minutes. Remove the baking tray from the oven and allow the cubes to cool completely.

Tips and warnings

  • For multiple colours, repeat the whole process, using clean ice cube trays and separate baggies for each colour.
  • Add the drops of food colouring down the side of the baggie on the inside instead of directly on the sugar.
  • You can also let your sugar cubes air dry for five hours after you remove them from the trays instead of baking them.
