Edible slime recipe

Makes 1 large ball or 2 smaller balls  Prep 15 mins  No cook

200g cornflour, sieved
50g icing sugar 
175ml coconut milk (from a can), stirred 
a few drops gel food colouring 

1. Put all the ingredients in a bowl and mix with a spoon until you have a smooth, thick paste. Once the slime has come together, use your hands to roll a little of the mixture into a ball. If it crumbles, add a little more coconut milk, 1 tablespoon at a time. If it’s too soft or liquid, add a little more cornflour until it’s pliable and stretchy.

2. The slime can dry out a little as you play with it. If this happens, simply knead with wet hands to soften it up again. 

Top tips for making edible slime

  • If the slime firms up too much while you’re kneading it, add extra water or coconut milk to loosen. 
  • For the best finish, add gel food colourings rather than liquid versions. They’ll give a stronger colour without altering the consistency. If you are using liquid food colouring, add a little more cornflour until you get the desired texture.
