I have observed this personally in my extended family. My paternal grandmother has 3 daughters. GM and Daughter 1's pickles would last long and were delicious.

I have observed this personally in my extended family. My paternal grandmother has 3 daughters. GM and Daughter 1's pickles would last long and were delicious. Daughter 2 and 3's pickles would not be good and spoil. But, the process, and I mean, like an industrial quality detailed process of pages and pages of notes and quantities, etc would be absolutely same. My GM always said 2 & 3 dont have the 'hand' for a pickle. Fun Memory : One of my grandmother most precious possessions was not gold or money, but a 40 year old aluminum tumbler, passed on to her by her mother-in-law, that was used to measure items for the pickle (x tumblers of mustard powder, Y tumblers of chilli powder..)
