Grease a parchment with coconut oil or olive oil and line a baking tray.
Boil your cup of water. If you are using marshmallow root, steep it in the boiled water for 15 minutes, then strain. If not using, just go to the next step.
Take 1/2 a cup of the water and put in a deep mixing bowl with the gelatin powder. Mix until well combined (about a minute, nice and super thick gloop) and leave there.
Take the other 1/2 cup of water and put back into the saucepan with the cup of syrup of choice.
Heat on medium (NOT HIGHER) until it gets to 110C or 230F – This might take up to 15-20 minutes on medium but is important to respect this step, as it’s about the slight evaporation of water over this length of time, as much as the temperature itself. Sounds complicated. It’s not.
Once you’ve achieved that temperature, you can then start pouring it super slowly (think ‘thin drizzle’) into the gelatin / water mixing bowl, mixing on medium the whole time.
Once the liquids are all incorporated, add vanilla bean and mix for another 30 seconds on high.
NOTE: If it’s not a super thick ‘mass’ of fluffiness yet, keep mixing possibly up to 10 minutes.
Then quickly pour out onto the tray, lined with parchment and spread.
DO NOT REFRIGERATE. Just let it cool and set. This will take between 2 hours – 8 hours depending on where you are in the world. Here in Sydney, it took 2 hours.
Now you can wipe olive or coconut oil onto a cutting knife and cut your cubes
Finally, dust with a starch – tapioca, arrowroot or organic corn flour, for that authentic marshmallow feel (optional, though)
Keep in a container in the pantry up to 10 days – if they can last that long at your house!
