Classic Bath Bombs

Bath bombs are pure joy to make, and they use two of my simplest ingredients — bicarbonate of soda and citric acid. Here's the classic recipe to get you fizzing.

You'll need (makes about 4–6 bombs)

  • Bicarbonate of Soda — 200g (2 parts)
  • Citric Acid — 100g (1 part)
  • A carrier oil or melted butter — 2–3 tsp (about 15g); sweet almond oil or melted shea are lovely
  • Witch hazel in a small spritz bottle
  • Optional: essential oil for scent (10–15 drops), a natural colour, a few dried flowers

Method

  1. Whisk the bicarbonate of soda and citric acid together really well, breaking up any lumps.
  2. Stir in the oil (and your essential oil and colour, if using).
  3. Spritz with witch hazel a little at a time, mixing quickly, until the mix just holds together when you squeeze it — like damp sand. Go slowly; too much and it'll start to fizz.
  4. Pack firmly into your moulds, leave for a minute, then turn out gently.
  5. Leave to dry overnight before wrapping.

A few tips

Humidity is the enemy of a good bath bomb — make them on a dry day, and store them somewhere dry. If your mix fizzes as you make it, you've added the witch hazel too fast.
