*Sometimes during the fermentation process you’ll see a white film form on the top of the brine. This is called scum and is harmless. Use a sieve to scoop off any film you see. *Instead of adding sugar, try adding a ¼ cup asian pear, julienned. *You can also experiment with different vegetables and amounts to your taste. Just be sure to keep the salt to water ratio in the brine the same. Salt helps keep the bad bacteria away and helps the good bacteria to flourish. *Ideal fermentation temperature is between 55 and 75ºF. When fermenting in a room temperature at the warmer end of the spectrum the fermentation process happens faster. On the cooler end of the spectrum it will take longer to ferment.
