Video de la receta


  1. Dissolve sugar in about 2 cups of boiling water. Add the tip of a teaspoon of blackstrap molasses (if using) and stir.
  2. Add fresh water to make ~700-750 ml total volume, and make sure the temperature is 104ºF (40ºC) or lower.
  3. Pour the sugary water into a glass Fido jar, add  two pinches of baking soda and the ginger slice (if using). Stir and add the kefir grains. Stir again and cap the jar. Set aside.
  4. Ferment for 24 hours and taste. Continue fermenting until the solution looks bubbly and active (it takes ~4 days for me, but the temperature in San Francisco is on the cold side). When ready, strain through a fine-mesh strainer and collect into a glass jar.
  5. Mix the fermented solution with the blood orange juice and transfer the mixture to flip-top sealable bottles for a second round of fermentation, and allow it to get fizzy. Continue to ferment for another day or two, tasting frequently to find the time you like it best.
  6. Let it cool in the refrigerator for a couple of hours and enjoy.
  7. Rinse grains that remained in the strainer and store in the refrigerator in fresh sugary water or start a new batch.

What are the benefits of this dish?

Although water kefir grains are similar in form to milk kefir grains, they are not directly related. Water kefir grains are also known as tibicos, and are a symbiotic community of mainly lactic acid bacteria and yeast held together in a sugar matrix created by the bacteria.

Kefir is a wonderful alternative to soda or juice and provides many of the hydrating benefits of drinking water.
