Serving Size 12 (4oz) bars

Equipment

  • digital kitchen scale
  • stainless steel pot
  • wooden or metal spoons
  • rubber gloves
  • digital thermometer
  • immersion blender
  • soap molds OR shoe box lined with parchment paper

Ingredients

  • 12 oz olive oil
  • 11 oz tallow
  • 10 oz coconut oil
  • 4.51 oz sodium hydroxide (lye)
  • 12 oz chamomile tea + water
  • 1 oz chamomile essential oil (optional)
  • 2 tbsps dried chamomile flowers

For the chamomile tea

  • 1 tbsp dried chamomile flowers
  • 1 cup filtered water

Instructions

  • Steep 1 tbsp dried chamomile flowers in just-boiled water for 10–15 minutes. Strain, squeeze out the flowers, and save them. Top up the tea with cool water to make 12 oz total of liquid. Let cool completely.
  • Gently melt coconut oil and tallow in a stainless steel pot.
  • Pour in olive oil and stir to combine.
  • Outdoors or by an open window, slowly add lye to the cooled chamomile tea. Stir until fully dissolved, then bring back inside.
  • Let the melted oils and the lye solution to cool to 100–110°F (37–43°C).
  • Pour lye solution into oils and stir gently.
  • Using your immersion blender alternate blending and stirring until the mixture thickens slightly, like thin custard. When you drizzle some of the mixture on top, you should see a faint trail on the surface - this means your soap is at light trace, so proceed to the next step.
  • Stir in the squeezed chamomile flowers (left over from making the tea) and essential oil. Blend briefly to combine.
  • Pour soap into a lined mold, smooth the top, and sprinkle dried chamomile flowers. Press lightly to stick.
  • Cover with plastic and wrap in towels or a blanket. Leave 24–48 hours to harden.
  • Unmold and slice into 12 bars when firm but still a little soft. Trim if desired.
  • Place bars on a rack or board with good airflow. Cure 4–6 weeks before using.

Notes

  • This soap contains 10% lye discount, making it gentle enough to be used as hand soap or bath soap.
