Soak the gelatine in 3 tbsp of water.
Alternatively, prepare the gelatine according to instructions, using the amount that suffices 1 cup of liquid.
Take the orange, peel it, and cut it into pieces.
Put it in a pot, together with 2 cups of water.
Add in 5 tbsp.
of erythritol, two tea bags, and bring to a boil.
Using a spoon, try to squeeze as much juice out of the orange as possible.
If you want, you can use 2 cups of 100% orange juice.
Keep in mind, this option is not too keto friendly, though.
Pour the “tea” through a fine sieve into 2 separate cups, filing each with 1 cup of the liquid.
Add 3 tbsp of sugar-free orange jam, and ½ tsp of orange oil (or 1 tsp of orange zest) into each cup.
Mix well.
Add the gelatine to one of the cups.
Do this while the liquid is still hot.
Mix well.
Set both cups aside.
Let them cool, and the jelly thicken.
