Ingredients

  • About 2 tbsp vegetable oil
  • Cornflour to dust
  • Ccocoa powder to dust
  • 8 tsp powdered gelatine 12g, plus 2 tbsp cold water
  • 280 g liquid glucose
  • 460 g caster sugar
  • 300 ml water
  • 100 g cocoa powder

Instructions

  • First, grease your tin well. Add vegetable oil and use clean fingers to evenly coat the tin. I would suggest a 30x20cm rectangular tin. Then dust the tin liberally with cornflour and cocoa powder.
  • Place the gelatine into a large heatproof bowl (ideally the bowl of a stand mixer if you have one). Add the 2 tbsp cold water and mix well. Set aside.
  • Next, add the glucose syrup and caster sugar to a large saucepan. Pour in 150ml water and place over a medium heat. Stir gently until the sugar has dissolved in the water. Once the mix begins to simmer, stop stirring. Continue to heat over a medium-high heat, gently swirling the pan, until the sugar syrup reaches 115C (use a jam thermometer to check). At this stage the liquid should be clear and bubbling. Handle the pan carefully as it will be extremely hot.
  • Remove the pan from the heat and very carefully drizzle the sugar syrup into the gelatine whilst whisking with an electric whisk. You will find this easiest if you use a stand mixer fitted with the whisk attachment.
  • Once all has been added, whisk on medium-high speed for a further 12-14 minutes - or until you have a thick, white meringue-like texture.
  • Sieve the 100g cocoa powder into the mixture and fold together.
  • Spoon the mixture into the prepared tin and smooth over the top using a spatula or palette knife. Leave to set for at least 2 hours.
  • Dust a baking tray or board with cornflour and cocoa powder. Tip the marshmallows onto the tray. Dust a large sharp knife with cocoa-cornflour then cut the marshmallow into equal-sized cubes. Toss to coat each one in the cocoa-sugar cornflour.

Notes

See the Step by Step guide with images to help you with this recipe. 
To store: Make sure each individual marshmallow is liberally coated in the icing-cornflour mix as that stops them all sticking together in the container. They need to be in an airtight container and I would layer with greaseproof paper if stacking in layers, to avoid any sticking.  They will keep for up to 3 weeks in a sealed container in a cool, dry place.
To freeze: Freeze in an airtight container. They will last up to 3 months. They do keep for a few weeks at room temp (not frozen) so you may not need to freeze them.
Make ahead: these homemade marshmallows keep well in an airtight container in a cool place for up to 3 weeks.
Size: you can cut the marshmallows into whatever size you like. Sometimes I make jumbo marshmallows, other times I make mini marshmallows. You can also use different sized tupperwares to alter the depth.
Make without sugar thermometer: If you are making without a sugar thermometer, scroll up to FAQs to see how it's done. You will need to use the cold water method.
