  • In a large mixing bowl, combine the baking soda, epsom salt, citric acid and tapioca starch. Mix well.
  • In a separate small bowl, add the sweet almond oil and rose water. Mix well.
  • Very (very!) slowly and gently, pour the wet mixture into the dry mixture, while stirring constantly. Do not pour too fast or you will prematurely activate the citric acid and you will be unable to mold the bath bombs. The mixture should resemble damp sand and should hold together if you pick some up and squeeze it, yet not be too dry and crumbly or too wet and crumbly.
  • Once the wet and dry ingredients are incorporated, gently fold in the calendula and rose petals.
  • Using your hands, gently pack each half of a bath bomb mold, overfilling slightly. Press each half together firmly and let it rest for 1 hour. Repeat until you use all of the bath bomb mixture.
  • Once the molds have rested an hour, gently tap the outside of the molds, then carefully pull the mold pieces apart until you release your bath bombs. Let the bath bombs rest in a dry place overnight, or at least 8 hours, before storing and using.


If you do not have bath bomb bolds, you can use silicone ice cube trays, silicone molds of any shape or even plastic easter eggs to shape your bath bombs.
