I followed a recipe based on 3-2-1 ratio of water-vinegar-sugar. I boiled the water, added the vinegar and sugar, whisked until the sugar dissolved, let it cool a bit, and added seasonings.
I then poured the liquid over fresh vegetables (cucumbers, peppers, carrots, beets, radishes) in jars, sealed the jars, and processed them for 25 minutes in boiling water.
However, while they were in the bath, I did further research, and found that the 3-2-1 ratio was not considered safe (with some exceptions). A minimum of 1:1 ratio of water to vinegar is now the recommendation.
I realize that I cannot treat these as canned. Can I immediately put them in the refrigerator, and eat them out of the jar? That was the intent of the original recipe: instead of processing the jars in boiling water, just put them in the refrigerator. And it does seem that the ratio I used is okay so long as you put it in the refrigerator, instead of storing it at room temperature.
Did boiling the jars create any health risks?
