I want to make a culture that only contains as least yeast as possible. i want to create my own starter by using salt ( moderate ) and vinegar/ lemon. from what i heard low PH keeps most yeast species and other stuff at bay.
i know how much % salt i can use but my question is ''how much lemon or distilled vinegar cani i use'' - i don't want the Ph too low and i don't want it too high.
a tablespoon of lemon juice in 250 grams of solution ? what is the best amount ?
