1½ cups bicarbonate of soda
¾ cup powdered citric acid
Small and medium mixing bowls
2 tsp herbal tea leaves (try chamomile, lemon, rosehip, peppermint)
Essential oil of your choice
Sweet almond oil
Moulds (mini-muffin tray or ice-cube tray)
Paper or foil cupcake cases
Raffia or ribbon
1 Sieve the bicarb soda and citric acid into a medium bowl.
2 Transfer ½ cup of the sieved ingredients to another medium bowl and add a pinch of tea leaves. Stir to combine. Set aside.
3 In a small bowl, combine 6 drops of your essential oil with Â½ teaspoon of sweet almond oil. Add 8-12 drops of food colouring (or as much as you need to achieve the strength of colour you desire). Pour the oil mixture into the reserved ½ cup of sieved ingredients and, working quickly to avoid fizzing, stir to combine the wet and dry ingredients.
4 Wearing rubber gloves, use your fingertips to further combine the ingredients and to evenly distribute the oils through the mixture. Continue to do this until the ingredients hold together when shaped. Wipe the moulds with paper towel lightly dampened with almond oil. Tightly pack each mould with bath-bomb mixture.
5 Repeat steps 2-4 another 4 times or until you have moulded the remaining bath-bomb mixture.6 Leave each bath bomb to set overnight. Working on a flat surface, firmly tap the tray down once, then gently ease out each bath bomb. Put each bath bomb in a paper or foil cupcake case or store them in an airtight container or jar. For a gift, wrap the bath bombs in mesh wrap and finish with raffia, or tie a tag to the jar with ribbon.
