Take the flour in a large bowl.
To the flour add the required amount of salt.
Pour water into the flour and 3 tablespoon of vegetable oil in it.
Knead the dough evenly, if required more oil can be added.
If it is sticky, add more flour.
When a soft consistency is attained, make the dough into small sections with craters.
In the craters pour the food colors.
Use a glove ( I have used a surgical glove, as we have a bunch always at home, kitchen gloves also work fine) to mix individual dough. Please lubricate the gloves with oil, as the dough may stick with the glove.
Please use separate glove for each color or wash after mixing each color.
Alternative method, the dough can be placed in a zip lock polythene bag, close the zip and knead the dough into the color required.
Viola!!! Your Edible Play Dough is ready!!!
