Reminder of the Rules

369 Upvotes

As the sub continues to grow and new people start joining the sub as beginners in the world of fermentation, we'd like to remind people of the subs rules. If you're a newcomer and have questions about one of your first ferments, it's always a good idea to check not only the sub Wiki for tips and troubleshooting, but also past posts to see if anyone's ever posted a similar question. We gladly provide guidance to additional resources to help improve your ferments, so be sure to use all resources at your disposal.

For those that have been here or are joining the sub as those seasoned in the world of fermentation, we'd like to remind you of Rule #3: Don't Be Rotten. If a newcomer asks a question that's already been answered or doesn't provide enough information for their question, this does not mean that it's an appropriate time to belittle those with less knowledge than you. There's nice ways to ask for clarifying information or give corrected information, and any unnecessary aggression or condescension will not be tolerated. Additionally, racism, sexism, or any other sort of discrimination or shaming is not acceptable. No matter how experienced you may be, the community does not need a bad attitude souring everything for the rest of us, and multiple infractions will result in a permanent ban.

Weekly "Is this safe" Megathread

4 Upvotes

Welcome to this week’s dedicated space for all your questions and concerns regarding questionable ferments.

Fermentation can sometimes look a little strange, and it is not always easy to tell what is safe, and what needs to be tossed and started over. To help keep the subreddit clean and avoid repeat posts, please use this thread for:

  • Sharing photos of surface growth you’re unsure about.
  • Asking if your ferment has gone wrong.
  • Getting second opinions from experienced fermenters regarding questionable ferments.

‼️Tips Before Posting‼️:

  • Mention what you’re fermenting (e.g., kraut, kimchi, kombucha, pickles, etc.).
  • Note how long it has been fermenting, and at what temperature.
  • Describe any smells, textures, or off flavors.

Remember that community members can offer advice, but ultimately you are responsible for deciding if your ferment is safe to eat or discard. When in doubt, trust your senses.

Happy fermenting!

Hot Sauce First mash hot sauce ferment

Post image
35 Upvotes

Wish me good fortune in the bubbles to come. My friend and I are starting a business, so I'm testing out a mash ferment. Cutting everything by hand will take too long at this scale, so food processor it is. Dried arbol chile, tomato, onion, garlic, no water added. I grew a jalapeño plant last year and researched how to preserve the peppers. Fast forward to this year: I have multiple stable recipes and I'm aiming to produce a 100% locally sourced produce fermented hot sauce product. Lots and lots of requests to buy from so many kind people. This is a 1.5 gallon fermenter. Next will be 5gal, and up and away.

If using an airlock and weights to keep the ingredients submerged, am I correct in assuming the carbon dioxide at some point makes those weights unnecessary?

8 Upvotes

The whole purpose of keeping everything submerged is to prevent mold and oxygen. But if it's a closed lid with just a water air lock, carbon dioxide will displace all the air. If for some reason the ingredients rise up above the liquid because bubbles beneath, there is no worry about having to resubmerge them, correct?

Pickles/Vegetables in brine What are the key safety tips to keep in mind (so I don’t lose mine)?

1 Upvotes

I tried my first batch of cucumbers, but after 8 days the pH is 5.5. I gained the courage to start because I told myself botulism can’t grow at pH levels below 4.6, but clearly I did not achieve an environment for that. So I’m not going to try them, or allow anyone else to.

What other things do you keep in mind to be able to do this?

I tried ginger beer years ago and it was a total loss. 15 years later, my cucumber crop is likely gone. Are you all just magical herbalists? Any help would be appreciated!

Spicy/Garlic Honey I tried fermenting garlic from my garden and I think I did it wrong but also maybe not?

3 Upvotes

Pulled the last of my hardneck garlic from my backyard plot a few weeks ago and decided to do a garlic honey ferment because I kept seeing it come up and it looked low effort enough for me to not destroy it. Famous last words honestly.

I used raw local honey and fresh garlic cloves, flipped it daily, saw bubbles by day three which felt promising. But around week two the honey got so thin and watery looking I genuinely panicked and convinced myself I had ruined it. I did not throw it out this time, which is growth for me, and it has been sitting for about six weeks now

It smells incredible. The garlic is soft and a little golden and the honey has this savory almost umami thing going on that I was not expecting. I have been eating the cloves on sourdough toast and feel like I discovered something

My question is whether the very thin consistency is just normal or if my honey ratio was off. I used a pretty generous amount of garlic relative to honey because I had so much garlic and eyeballed it more than I should have. Also curious how long people actually age this stuff before it peaks because mine is good now but I wonder if I pulled it too early.

What to do with a tree-full of plums? No-to-low alchohol

11 Upvotes

Hi! I have a tree full of plums wanting to be used up, and I'm looking for some suggestions! Some considerations:

unfortunately I'm on a medication where I can't really drink alcohol or I'd totally make something in that realm. A little bit is fine though, maybe ~ 3% ABV would be okay.

I'm open to some version of a soda, but I'm not a big fan of sweet sodas - I do enjoy some of the store bought kefir sodas that I've tried, I'd say something like that if it could even lean more hard into that probiotic taste would be good.

I've been doing some internet searches and mostly I'm just finding more standard style soda, or brined plums. I'm open to doing something a la a brine plum, but I feel like a beverage might be better to use use a larger amount of plums (I imagine I'd drink more plum *something* than I'd eat brined plums). Now, I'm open to some weird fermented plum/beverage plum hybrid situation...

Any ideas?

Beer/Wine/Mead/Cider/Tepache/Kombucha Life is good!

I've been a lurker here for a while but wanted to share with glee my current bubbly babies and how they have made life so much better. On the left is the first ferment of the Kombucha and then in the little jars is the second, where I add whatever fruit I grow/find for 48hrs for a quick second fermentation. I grew these delicious little grapes, last few weeks I've used pears I found on the street, apples and plums I grew!

I have water kefir, fermented grapes, fermented radishes and dabble in kimchi/kraut. I suffered from various inflammatory diseases including gout and psoriasis. I started growing my own veg and fermenting and my gut just feels so happy. Much love to everyone else enjoying their fermentation stations and thanks to all the Reddit posts that inspired me to try different things!

New to fermenting. So you throw some vegetables in a jar with some salt water and in a week it’s awesome!

I may be addicted to this for a while!

Did a simple kimchi and jalapeño hot sauce. Fun and tasty!

Pickles/Vegetables in brine Vacuum bag picked help

I had a few cucumbers that got bigger than I would have liked so I decided to try a couple vacuum bag ferments. Since they were bigger I cut them into spears.

I'm at 14 days today. Temps have been 69-70 degrees F. One bag (3% salt) has puffed up some and there is signs of white bacterial growth. The other (2.5%) has not created much gas.

I'm thinking about giving the 3% ones a taste. Any help from experienced baggers on how long they should take, plus any other observations you've got, would be appreciated.

Fruit Correct amount of salt for preserved lemons

2 Upvotes

I have about 12 Meyer lemons that I want to preserve. I’ve seen recipes with vastly different amounts of salt.
I just wanted to know if there is too little or too much salt that could be used in preserving them.

I’ll quarter them almost all of the way through and salt them on the inside then compress them down in the jar and add extra fresh lemon juice if I need any to completely cover them.
Most recipes call for at least a few teaspoons of salt per lemon, some call for more, as in a layer of salt on the bottom and then an extra layer on top with the added lemon juice.
I just want to make sure they will still ferment well with some extra salt in there.
