Mix one cup of kombucha and the agar powder in a bowl.
Pour into a pot and turn the burner onto low and stir well until it dissolves, about 3-5 minutes.
Add the maple syrup, open your probiotics capsules, and pour the contents into the pot. Mix well on low heat for another 1-2 minutes. Do NOT boil the kombucha and probiotics, keep it on low heat to not destroy the good stuff.
Remove the pan from the heat. Add the other cup of kombucha and stir well until there are no lumps at all.
Select a mold, or line a shallow pan with parchment so you can lift them out and cut them into cubes after. Pour the mixture into your mold/pan and place in the fridge to set for 2-3 hours.
Once they are set, pop them out and store them in a glass, airtight container for 2 weeks.
