Once you try homemade marshmallows, there is no way back!! They are like nothing you have experienced before- I promise! Bouncy, fresh and so so soft. Making them feels very rewarding and the results are as sooo satisfying . You will need a candy thermometer for this recipe though. Find it below.
Adapted from the book New York, by Marc Grossman.
Ingredients
- 80grs icing sugar
- 4 ½ tsp cornflower
- 35grs powdered gelatin
- 240ml water
- 450grs sugar
- 175grs glucose or sugar cane syrup, (i used corn syrup as it’s what I had at hand)
- 2 egg whites
- 1 pinch salt
- 3tsp vanilla extract, (or other flavoring)

METHOD
The Tin
- 1)
Combine the icing sugar and the cornflower.
- 2)
Oil a 25cm (10inch) square tin and sift about 3/4 of the sugar-cornflower mixture over the oiled surface.
The Mixture
- 1)
Sprinkle the gelatin over half the water, don’t stir, leave aside.
- 2)
Place the sugar, glucose syrup and remaining water in a pot over medium heat, stirring until the sugar dissolves.
- 3)
Bring to the boil, then lower the heat to keep on a very gentle simmer for about 15min. Don’t stir. Use a pastry brush dipped in water to clear the inner sides of the pan from crystallizing sugar.
- 4)
Cook to 120C- 250F (candy thermometer) and remove from heat.
- 5)
Add the gelatin to the sugar mixture and whisk until completely dissolved and combined.
- 6)
Beat the egg whites with a pinch of salt to stiff peaks (use whisk attachment)
- 7)
Beat the gelatin- sugar mixture with electric beater (beaters attachment) until more than double in size.
- 8)
Gently fold in the egg whites and flavoring.
Setting and Serving
- 1)
Pour the mixture into the tin, smooth the top and dust with the remaining icing sugar-cornflower mix.
- 2)
Let it sit at room temperature for about 5 hours. Don’t be tempted to remove it earlier!
- 3)
Gently use your fingers to separate the marshmallow from the tin. Turn it onto a baking paper and use a (carefully) buttered sharp knife to cut into little cubes.
- 4)
I rolled them in the extra icing sugar- cornflower mix to avoid the little pieces from sticking together.
- 5)
Store in an airtight jar.
