2 x 7g sachets of powdered gelatine
450g caster sugar, plus an extra two tbsp.
2 tsp vanilla extract
2 egg yolks
50g icing sugar, plus extra for dredging
50g cornflour, plus extra for dredging
Fill a bowl with 100ml of cold water and insert the gelatine – set aside for 10 minutes or until the gelatine has softened.
Add the raspberries to a saucepan and cook on a medium heat with two tbsp. of caster sugar.
Mix together until the sugar dissolves and the raspberries turn to a coulis.
Take off the heat and pass the raspberry coulis through a sieve to remove any seeds.
Take a large heavy-based saucepan and pour in the sugar and 175ml of cold water and bring to the boil on a medium heat – stir continuously until the sugar dissolves.
Reduce the hob temperature and simmer the mixture gently for 15-20 minutes – place a sugar thermometer it in to the mixture and wait until the temperature reads 113°C.
TIP: This mixture is extremely hot and dangerous so be careful.
Remove the gelatine from the cold water, squeeze any excess water out and add to the sugar syrup mixture and stir.
Place two egg yolks in to the food blender and whisk together on a low setting.
In a slow and steady stream, gradually pour the sugar syrup mixture in to the food blender and whisk continuously until all of the syrup has been incorporated.
Add in the vanilla extract and then increase the speed to a medium setting and leave for around 18-20 minutes.
In a small bowl mix together the icing sugar and cornflour and dust your marshmallow pan with the mixture.
Once the mixture has turned in to a soft mallow stir in the raspberry coulis.
Pour the marshmallow mixture in to the pan and use a spatula to smooth the mixture down. Dust the top of the marshmallows with a little more of the icing sugar and cornflour mixture.
Leave the marshmallow to set for one or two hours or even better overnight.
TIP: Do Not Chill in the fridge!
Once set, fold down the collapsible sides and use the handy guidelines to cut out individual marshmallow squares using our marshmallow cutter.
