Combine the dry ingredients in a bowl and stir until well mixed.
Drizzle in the almond oil and stir until mixture is moistened. Add more oil and fragrance and stir until well mixed.
If the mixture is crumbly then add more oil or a dash of water.
Roll the mixture into a ball using your hands or press it into a lightly oiled mold. Use a bath bomb mold or a chocolate mold.
