My take on the gelatin low cal marshmallow

Made the version from this video, previously shared here: https://www.instagram.com/reel/DKbKj5LNdzy/
But beef gelatin is quite expensive here, so to lower the calories, I've used flavored gelatin too:
– 20g grape flavored gelatin;
– 20g beef gelatin;
– 150ml boiling water;
– 150ml room temp water;
– Any preferred sweetener.

1. Mix all gelatin with 150ml room temp water;
2. Boil 150ml of water with your sweetener;
3. Mix until fluffy. You will know its ready when you turn the bowl upside down and the gelatin doesn't drop;

Whole batch was around 150 kcal.
