- 60 ml Water (For blooming gelatin)
- 140 g Liquid Glucose (Half a cup; sold in tubes in the baking section)
- 150 g Caster Sugar (Fine‑grained sugar for syrup)
- 120 ml Water (For sugar syrup)
- 2 tsp Vanilla Extract (Pure vanilla extract for flavor)
- 1 cup Cornstarch (For dusting the finished marshmallows)
- 1 cup Icing Sugar (For dusting the finished marshmallows)
- 1 tsp Flavorless Oil (For greasing the tin; use a neutral oil such as vegetable oil)
- 1 sheet Cling Film (To line the 8×8 tin)
Instructions
Bloom the Gelatin
Combine 24 g powdered gelatin with ¼ cup (60 ml) water in a small bowl, whisk briefly and let sit for at least 5 minutes until it becomes a grainy jelly.
Time: PT5M
Melt the Gelatin
Place the bloomed gelatin in a microwave‑safe bowl and heat on high for about 30 seconds, then stir until fully liquid.
Time: PT1M
Prepare the Sugar Syrup
In a deep saucepan combine ¾ cup (150 g) caster sugar, ½ cup (120 ml) water and half of the liquid glucose (≈70 g). Heat over medium heat, stirring until sugar dissolves, then attach the candy thermometer.
Time: PT10M
Heat Syrup to Target Temperature
Continue heating the syrup until the thermometer reads between 112 °C and 115 °C (233‑239 °F).
Time: PT5M
Temperature: 112-115°C
Start Mixer on Low
While the syrup is heating, set the hand mixer with the whisk attachment to the lowest speed.
Time: PT1M
Combine Gelatin and First Half of Glucose
Pour the melted gelatin into the mixing bowl, add the remaining half of the liquid glucose, and whisk on low for about 1 minute until smooth.
Time: PT1M
Add Hot Syrup to Mixer
When the syrup reaches the target temperature, slowly drizzle it into the mixing bowl while the mixer runs on low.
Time: PT2M
Whisk on Medium‑High
Increase the mixer speed to medium‑high and whisk for 5 minutes. The mixture will become opaque and increase in volume.
Time: PT5M
Whisk on High Speed
Turn the mixer to the highest speed and continue whisking for another 5 minutes until the marshmallow mass is thick, glossy and holds stiff peaks.
Time: PT5M
Add Vanilla
Add 2 tsp vanilla extract and whisk on high for an additional 2 minutes until fully incorporated.
Time: PT2M
Transfer to Prepared Tin
Line an 8×8‑inch tin with cling film, grease lightly with flavorless oil, then quickly pour the marshmallow mixture into the tin and smooth the top with a greased spatula.
Time: PT2M
Dust the Surface
Mix equal parts cornstarch and icing sugar (about 1 cup each) and generously dust the top of the marshmallow slab.
Time: PT2M
Set at Room Temperature
Leave the tin uncovered at room temperature for at least 4 hours (or overnight) until the marshmallows are firm to the touch.
Time: PT4H
Unmold and Cut
Remove the cling film, place the slab on a dusted surface, and cut into squares using a sharp knife that has been dipped in hot water and dried.
Time: PT5M
Final Toss in Dusting Mix
Toss each marshmallow piece in the remaining cornstarch‑icing‑sugar mixture to coat all sides, then shake off excess.
Time: PT5M
