I few months ago I asked advice to preserve the many heads of garlic I had : https://jlai.lu/post/253034
The reponses included to freeze it, to make confit or to preserved it in salted water or oil.
I've tried every methods, but confit that's on my list for next time I have garlic, and I've been consuming fermented garlic.
I'm very proud of that first attempt at salt fermentation (^_^)
More recently I've decided to taste my garlicky oil and I've open one of the jars. The bubbling oil was so active it splash a bit around. So I close it wondering what I have done wrong : 3 months ago, I've peel the skin that was on the older garlic heads, cut any bad looking part, place the garlic with some fresh thyme, fill the jar with olive oil and store it lip tight on a dark shelf.
So first : Thank you for all the idea. It was fun, tasty and avoid plenty of waste.
Second : Do you know what is wrong with the garlic preserved in oil ? Is it simply carbonic gaz from the fermentation that build up ? Should I have blanch my garlic or dried my thyme before hand ?
Thank you again for you precious help
Do not eat the garlic stored in oil! Garlic and oil is a botulism risk if stored at over 40° F or for more than 7 days. Garlic is a natural reservoir for botulism and the oxygen free environment of oil gives it everything it needs to grow to dangerous levels.
Oh… How could I miss such an important warning when researching for preserving method (-_-) I haven’t eat any of it but now I worry about having wasted half of the house garlic trying de preserve it.
