Ferment raw vegetables in 7 days! Traditional fermentation takes time, for the acidity to bring the food to a stable and edible condition. Caldwell’s vegetable starter culture is a result of 15 years of research and development and is specifically designed for vegetables. It contains the correct bacteria strains in ideal proportions and can speed-up fermentation in as little as 7 days with crispy results. Comes with 6 pouches. Each pouch prepares 4 1/2 lbs. of raw vegetables.
