Ingredients:
1/2 cup table salt
1 cup plain flour
1 tbsp cream of tartar (don’t ask me why)
1 tbsp of oil
splash of food colouring
3 drops of vanilla essence
1 cup of boiling water.
Put all the dry ingredients together in a bowl and add boiling water. Mix together well, add colouring and essence and when cool enough knead with hands until it reaches a good consistency not to sticky, not too dry. Sometimes I add more salt if it’s too wet or more oil if too dry. It does keep for ages in an airtight container. I have been know to add glitter too.
Addatum:
As myself and teawithonesugar found out DO NOT try to replace the cream of tartar with ordinary baking soda - you will indeed end up with a gloopy mess rather than a maleable dough
