I grew up on now what is my farm so I know pretty much what is.  That being said.  There are strict rules you go by. If you say any of thesethings or wonder in your mind walk away: That looks like just like... Humm these are starting to flush this early. Wow I never knew these grew in this type soil before... I wonder, those look just like. These only grew near oak trees.. humm (pick the tree) Perhaps the sun changed the color a little, they must be ok. How come these are..... The only good reason to pick is " Yes those are them and all conditions are met"  Just one small thing you question, Walk Away.... I've been eating the ones around here for 68 years and not dead yet.  Break just one rule or question yourself, not walk away or you just may suffer the results. Dave...         

It was likely vinegar.  It may now be rocket fuel.  😀

The crocks look very much like the ones used for the drying of anchovies.  I love picked, fermented and preserved things.

Good luck, happy hunting, and be safe. Sent from my iPhone using Tapatalk

Mrs. C complains about my fermentings, so I use the Korean double lid "stankless" vessels.
