Homemade Raisin Leaven

• 1 An airtight jar (sterilized by boiling)
• 100 grams Raisins (not coated with oil)
• 500 ml Water (filtered water)
• 5 grams Sugar (If fermentation is slow...)

1. Put the raisins and water in a sterilized air-tight jar.
2. Place the jar in a sunny spot near a window until it ferments.
3. As long as it's warm, anywhere is fine.
4. Stir the contents of the jar once a day and open the lid to refresh the air.
5. You should be able to hear fizzing once it starts to ferment.
6. Although it depends on the temperature, in 2 to 4 days, it should start to fizz.
7. If the fermentation (fizzing) takes longer than 4 days, add sugar.
