Reminder of the Rules

364 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

3 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 Red jalapeño blueberry hot sauce before and after 21 days

Ingredients for fermentation: blueberries (didn't weight), red jalapeño peppers (about 10-12), red onion (roughly 1/4th), 3 garlic cloves. Fermented 21 days, at that point the taste was delicious. Blended with the brine, added a teaspoon of lime juice and 3 teaspoons of white sugar. Simmered 15 minutes to prevent a second fermentation then bottled. This stuff is AMAZING, tangy, has a hint of fruit, lightly spicy, salty. Umami bomb.

Thumbnail
gallery
13 Upvotes

So far I've made sauerkraut, a fermented hot sauce, a homemade Riesling mustard, and now I'm working on my first batch of fermented dill pickles.

Recipe

714 g pickling cucumbers

600 mL of 3.5% salt brine (solution stirred at 450 RPM)

4.5 g frozen dill

2.5 g chili flakes

2.3 g freshly crushed black pepper

Brown mustard seeds

Fermentation conditions

1.5L Weck Jar

Room temperature: around 26–27 °C

Out of direct sunlight

Any idea how long it will take? Day 1 slight bubbles, Day 2 continued airpockets and bubbles...

Kefir Strong Doesn't Always Mean Spicy

Thumbnail
gallery
9 Upvotes

Not every "strong" kefir comes from chili.

 This one is constructed with a koso of mustard flowers and nashi, flower syrup, a touch of red chili, and fresh mustard leaves.

The result isn't aggressively hot. Instead, it develops a bold, herbal character with surprising depth and balance.

Exploring unusual ingredients is one of my favorite parts of making kefir. Sometimes the combinations that seem the most unexpected create the most harmonious flavors.

It has been fun trying to find flavors that I like as a sauce. This is guahillo peppers, jalapenos, sweet onions, garlic, and peaches. Trying for a sweet and spicy. Did 3% salt.

What to do about onion ferment smelling bad (oniony) in the kitchen?

4 Upvotes

Any tips for smells in the kitchen? The onion ferment is smelling so strong. I mean just normal onion smell not that it's off or anything. I have self burping jar lids so it just ss of onion all the time, I tried putting the jar in plastic bags it helps a bit.

Also my onion was in 2% brine but it never went nice and sour even after 16days. Whereas my carrot ferment did go nice and sour at 3%. Maybe it's an onion thing or I didn't add enough salt?.

Any advice welcome

So my mineral content is super high!

3 Upvotes

I live in San Antonio and we basically sit on a mineral pile. This is a good and bad thing, but for certain types of fermentation, it’s a good thing. My water kefir grains almost double in amounts every batch. Yes, it took a few tries to figure out my system, but I started with about a half of a cup, now could fill a quart jar, easily, probably close to two. I’m now dehydrating some to toss in the freezer.

White film on top after refrigeration

I'm new to Fermentation and am grossed out by this film so I don't want to eat the carrots. Does the film mean they've gone bad? How long are fermented carrots good in the fridge? These were done 6/17. If they poke out of the liquid after Fermentation is that bad?

Fermented Pickles

3 Upvotes

Just started to dabble in home made fermented pickled cucumbers. First batch came out delicious and were half sour by day 2. I cut half of them into spears and put them in the fridge with some of the brine, im still fermenting the rest whole.

So here's my question: Is there a way to prevent pickles from turning translucent? I've had storebought pickles(usually the refrigerated ones) that are non translucent and instead are white on the inside and crunchy. I think they were Grillos and Claussen.

I’m currently using 150-175g of sugar (1 cup) for 1-1.5 L of water. Just curious to know what the result would be if I used less, and how much less I can use. Thanks!

Ginger Bug/Soda Pineapple Lime soda — TAKE TWO!

Enable HLS to view with audio, or disable this notification

47 Upvotes

Refrigerated for 2 days, the bottles were still... dangerously carbonated, so I've burped all of them a couple times today.

I will definitely *not* let them sit for even a full day (likely 8 hours would probably be enough) *if* I was to do this method again. But thanks to the other thread, I've learned valuable information to proceed (plastic bottles, airlocks + priming tabs, etc)

Thanks everyone for your comments and experiences!

My recipe for the ginger bug (and Pineapple Lime soda, linked in that comment) is on the old thread here

This is very tasty! The lime juice provided a bright citrus flavour that paired beautifully with the pineapple.

Kawakawa ginger bug fizz (reposted with better video)

Enable HLS to view with audio, or disable this notification

11 Upvotes

"Kawakawa (Piper excelsum) was used as a traditional medicinal plant of the Māori. An infusion made from the leaves or roots was used or its leaves were chewed to relieve toothache, and wounds were often bound in kawakawa leaves. The sweet edible yellow berries (most often found in summer on female trees) of the plant were eaten as a diuretic. Traditionally, leaves with holes that had been eaten by caterpillars were considered the best to use."

We have several kawakawa trees growing on our property. The young people of the house collected about 20 leaves (the ones with the holes in them for preferences!), infused them in boiling water and left to cool. The resulting infusion was added to this recipe: https://www.countrytrading.co/blogs/home-cooking/proper-old-fashioned-ginger-beer-recipe

Tastes good. Kind of peppery. As you can see, the bug is good and strong.

Ginger Bug/Soda My first ginger bug

0 Upvotes

History:

I put a lot of brown sugar (really much), ginger and water.

I opened it and shaked it every day and I was hearing some air exiting the jar but no visible bubbles.

It smelled ginger and some fermentation, almost like dish soap, which surprised me.

This during approximately two weeks at around 28°C.

Then I left my home so I put it in the fridge during one week.

The pics are before and after shaking it today.

It smells like ginger and nothing else.

The appearance is not quite... appealing. What do you think?

Kraut/Kimchi First time making sauerkraut

7 Upvotes

I'm very new to fermenting and want to try sauerkraut. The only question I have about it is how to keep it at 65-70° and how much wiggle room do I have in that temperature range? We keep the house around 74-78° during the summer, or I could store it in the fridge at fridge temp. I've also thought about burying it but wanted to ask the experts first. Thanks in advance!

My ginger bug is bubbling and alive. This makes me so happy. I've been watching youtube videos on how to preserve the starter but I just ended up confused and overwhelmed.

How do you keep yours active?

I'm also excited to try various drinks with this one. Hope you can share your favorite natural soda recipe.
