1/2 cup of light oil (such as sunflower or sweet almond oil or even extra light olive oil)
1 tsp strawberry extract (allergy free)
8 drops of red food coloring (allergy free)
1 cup of baking soda
1 cup of citric acid powder
1/2 cup of corn starch
3 drops of green food coloring (allergy free)
1 strawberry shaped ice-cube tray
Blend the oil, strawberry extract and red food coloring. Combine baking soda, citric acid powder, cornstarch and oil to mixture until it forms a crumbly pink dough.
Pack the dough into the strawberry shaped ice-cube tray. Set overnight, the gently unmold. Pour 1 tbsp water into a small bowl and add the green food coloring. Dip a small paintbrush into the water. Blot the brush on a paper towel. Using the dry brush, lightly paint on the leaves on the top of the strawberry.
