Here's my best recipe so far:
- Brew some black tea extra strong.
- Pour 1 liter of the black tea into a 2 L bottle after it has cooled to about 135F or 60C (The warm temperature speeds up the water-absorption process).
- Pour in 200 ml of Chia seeds (or 10% of your final batch size) and shake immediately, or it will coagulate into a solid mass. Shake a few more times until about 5 minutes has passed.
- Pour in a few tablespoons of your previous batch (This speeds up the fermentation process).
- Pour in pure pomegranate juice to top up the 2L bottle. Shake again, and leave the bottle at room temperature with the lid on.
- Check for gas every few hours by loosening the cap, and listening for escaping gas. (This can take a few hours to a day or more).
- The batch is ready when the batch starts to lose sweetness, and much more gas is being produced. (Do this to personal taste and preference).
- Put in fridge to slow down the fermentation process. (It will continue much more slowly when refrigerated).
