5 rules to follow
1. Wash all utensils (and hands) with warm soapy water. Sterilization is not necessary.
2. Avoid salt with added iodine. This substance has antimicrobial properties that alter the fermentation processes.
3. Use still bottled mineral water. The one from the tap may contain chlorine which, being added to kill microorganisms, as well as iodine has the ability to slow down or block fermentation.
4. Keep the jars out of light: even ultraviolet rays have an antimicrobial action.
5. Check that the foods are fermenting always covered in liquid.
