Black Rose Marshmallows

These enticingly dark and soft homemade marshmallows are surprisingly easy to make with the aid of a stand mixer, and a world away from shop bought ones.
Servings: 32 marshmallows

Total Time40 mins

Ingredients

Marshmallow mixture

  • 2 sachets powdered gelatine - about 20g
  • 120 ml warm water
  • 440 g sugar
  • 100 g golden syrup
  • 200 ml water
  • 1 tsb Rose flavouring - Test amount needed
  • 1 tbsp activated charcoal - food grade
  • Black food colouring - Prefrably gel colour
  • Dark red food colouring - Prefrably gel colour

For dusting

  • 3 tbs activated charcoal - food grade
  • 3 tbs cocoa powder

Instructions

  • Mix the 120ml of warm water and the gelatine in the mixing bowl of your stand mixer.
  • Place the sugar, syrup and 200ml of water into a heavy saucepan and bring to the boil. Heat gently until the syrup has reached 120C.
  • Whilst the sugar is heating, line a baking pan (about 30 x 20cm) with oiled cling film (I pour a small dab of oil on to the film and then scrunch it up to coat it).
  • Slowly mix the water and gelatine mixture on a low speed with the whisk to prevent it from setting.
  • Once the sugar syrup has reached 120C increase the speed of the mixer to maximum and carefully pour the syrup over the gelatine.
  • With the mixer still whisking, add activated charcoal, colouring and rose flavouring. After they've been incorporated, test the mixture for flavour and add extra rose flavour as required.
  • Mix at high speed for about 10 minutes until bubble gum like strands form.
  • Pour into the prepared pan and leave at room temperature for 2 hours until set.
  • Mix the activated charcoal and cocoa powder and liberally dust a board with it, turn the set block of marshmallow out, teasing the cling film from it. With an oiled serrated knife cut the marshmallow into cubes dusting each freshly cut surface with the cocoa mix as you go. I found the cutting was the hardest part of the process, the marshmallow is fairly forgiving and robust so you can pull it around a fair bit.
