Step 1
In a small bowl, combine the gelatin with 120ml cold water. Stir gently and let it sit for about 10 minutes.
Step 2
In a saucepan, mix in sugar, 100ml water, and lemon juice. Bring it to a gentle boil, cook for 10 minutes and remove from heat.
Step 3
While it’s still hot, stir the hydrated gelatin directly in the pot. Beat the mixture for about 7 minutes, or until it’s thick and fluffy.
Step 4
Lightly grease a silicone mold with vegetable oil. Pour in half of the marshmallow mixture and smooth it out.
Step 5
Add a few drops of red food coloring to the remaining marshmallow batter and mix. Then pour this pink layer gently over the white layer in the mold and let it set at room temperature.
Step 6
In a bowl, mix powdered sugar and cornstarch and sprinkle over the marshmallow.
Step 7
Remove the marshmallow from the mold and cut into cubes.
