  1. Hi Ted,
    Love your web site, Nuferm has been a wholefood fermenting company for 8 years in Australia and 6 in Scotland. We are branching out to run some retreats as Fermenting foods is really taking off in Australia, especially in Nth Queensland. Your recipes are really inspiring and so easy to follow with your clean web site. We have Clive Lawler visiting today who is going t teach us all about Fermented Bread. So kinder on your tummy. Love fermented foods so healthy, so age reversing. Thanks Ted

  2. Hi Ted:

    Thanks for your website. I have used many of the recipes on your site (and variations thereof) and they are all great. I wanted to share something with you I hope you enjoy. I didn’t know where to send it so I hope here is ok. Have a great day!!

    Adam’s Fermented International Chimichurri Sauce

    I love the cuisines of Thailand (Thai basil), South American countries (cilantro and parsley), and middle eastern countries (parsley) and noticed they all had a version of chimichurri. I combined all three and then fermented it for a wonderful tasting and healthy condiment that keeps for months in your fridge. I hope you like it.

    2 bunches organic flat leaf parsley (the top part with the bottom section of the stems removed)
    2 bunches organic cilantro (the top part with the bottom section of the stems removed)
    3 bunches of thai basil (just the leaves; no stems)
    2 bunches of organic scallions
    8 cloves of garlic (or to taste)
    juice of 6 limes
    1 teaspoon of white pepper
    1 teaspoon of fermented hot sauce (or tabasco, crystal, or your favorite brand). A recipe for fermented hot sauce i have used (actually variations thereof) can be found at
    1 Tablespoon of fermented sauerkraut brine
    1 Tablespoon salt (I used himalayan pink salt)
    A small amount of 3% brine (just enough to cover the top after bottling)

    Roughly chop all the greens and all all the ingredients (not including the brine) in a food processor and finely chop.

    1. Wash the greens.
    2. Roughly chop all the greens and put all the ingredients (not including the brine) in a food processor and pulse until everything is finely chopped and well combined.
    3. Place the mixture into a mason jar (I equip mine with an air lock) and pack the mixture in tightly. Make sure you don’t fill the jar too full.
    4. Once the chimichurri is packed in tightly, gently pour 2-3 tablespoons of your brine (I used 19 grams of sea salt to 1 quart of water) over the top of the pesto. You just want enough to cover with a nice layer of brine.
    5. Add your airlock, close the lid, and let ferment in a dark place for 3-4 days and then move to cold storage.
    7. I have also used it like a pesto by adding grated parmesan cheese and olive oil to it.

    You can use it with with grilled chicken or steak, of course, but I also use it to flavor soups and sauces, add it to mayonnaise to make a sandwich spread, and use it together with siracha to make delicious deviled eggs.

    The best part is that it keeps in your fridge for at least three months (This is the longest I have ever kept it before eating it all so it probably lasts longer). After a month or so I pour a little olive oil over the top to keep it from browning, but even if you don’t do this you can just skim off the brown part and everything beneath is still wonderful.

    I used Jessica’s recipe for my base which can be found here for anyone interested (
    Peace y’all. Never stop thinking and living kindly!!

  3. Thanks Rick. No dumb questions in the fermenting world. 1 and 1/2. I’ve updated the recipe so the formatting of that is more clear.

    Best of luck and let us know how it goes.

  4. I’m trying this for the first time–one question, what if you used ground mustard? Would it work, and if so, how much by weight of mustard to kombucha?

    • I’m a bit of an experimenter, but I haven’t tried this yet as I tend to prefer mustard to have a little more texture. I may get around to it, but I also encourage you to just play around and see what happens. If you give it a go, please let us know how it goes and what you learn. Thanks!

      • I bought a tiny jar of McCormick mustard seeds and used my algebra to calculate the amount of kombucha vinegar and its in the cabinet now beginning its process. I’ll try it with some ground mustard and let you know how it goes!

  5. I had some success with my first tiny batch of Kombucha Mustard, but it was hotter than I like. Any clue how to mellow it out a bit? I added a little turmeric and heated it to stop the fermentation (hoping also that the heat would cool down the spicy-hotness–no luck) It does taste good, but I have to only use a tiny spread at a time, I’d really like it with less of a bite.

    • Hi Cyn. The heat in mustard can be dependent on several things. I’ve updated the post to reflect this so please re-load the page and re-read. Now that you’ve made the mustard and it’s still too hot, I’d try adding a little honey or sugar as that seems to take the bite out of hot things. Sourness can sometimes help too so perhaps a little lime juice or vinegar. Good luck!

      • I ended up adding a little hot water and blending it some more–still hot–but I put it in the back of the fridge and forgot about it for 6 months, then found it again and it was fine! No heat anymore, and just good mustard taste and texture.

  6. I am very excited to try this with my homemade sauerkraut! Can I use kombucha vinegar instead of the tea? I have quite a bit of vinegar right now. Thanks for sharing!

    • Sorry, a bit confused. you want to use vinegar to make sauerkraut? Replacing tea? help! The mustard lasts a long time in the refrigerator. It’s never gone bad on me, but I ate always eaten mine within a year.

      • I meant that I could pair your mustard with my sauerkraut, like in your sauerkraut avocado sandwich. I was wondering if I could replace the kombucha tea in your mustard recipe with kombucha vinegar. Thank you!!

  7. I made it and it came out great! Thanks for the recipe. I used the really vinegary tasting kombucha from my scoby hotel, and I used 1 part Indian black mustard seeds to 3 parts yellow.,I stone -ground it and added a tsp of garlic to the mix. Yum!

  8. I love your site. and I put a link on curezone, where I am active on the water satng forum. And lime pickle is my favourite condiment, maybe of all time. 🙂 I will try your recipe, maybe next new moon.
    Second to that, I am pining for some dijon-esque cultured mustard, and was thinking, maybe kombucha.
    The best kombucha I’ve made so far, (going on five or six years) is one that sat out on the cold veranda, all winter, in a little styrofoam cooler, with no lid. A few of the bottles broke, but the survivors were better than champagne. I added ginger and apricots when I bottled them, and put corks in them. Didn’t know any better. And left them outside because we got tired of kombucha … long story short, the following summer, I opened a bottle, with a friend, and we drank the whole thing. So so good.

    I have a little discovery I can share with you, as exchange for you sharing all your lovely work. Avocado pit– I grated some yesterday. am experimenting with it. Let it dry on the cutting board. It’s quite good. A spicy flavour. I’ve used it before to due fibre, but just learned how good it is, and thought, well, what about adding it to kombucha, or veg. ferments? With the tannins, it’s probably good for pickles, or to keep turnip crunchy. (?) Third favourite cultured thing on my mind is the middle eastern turnips. . . .

    When I first read Sandor Katz’ book Wild Fermentation, it was like coming home, somehow. Your site gives me the same good feeling. Thanks

  9. correction: I meant to write water “fasting” forum. People who get into water fasting tend to be those who come around to the beauty of cultured foods.

  10. Thanks for sharing all of these recipes! Can’t wait to try this one. I’m confused about what to do with the sugar, though. Do you put it in at the beginning when you first put the seeds and the kombucha in the jar, or at the end, with the salt, when it goes in the food processor? Thanks!

    • My apologies. I’ve adjusted the recipe to be more clear on that. Add the sugar with the kombucha and mustard seeds in the beginning. Good luck and happy fermenting!

      • Thank you and please don’t apologize! I love your recipes and so appreciate your making them available to people AND answering questions about them! Trying your “Sivakraut” today–can’t wait.

        • I don’t know why the computer is giving me an angry blue face–it isn’t offering me a choice that I can see… Please picture happy face instead.

  11. Thank you for the idae!
    I made a quart and then split it into two batches,
    1. A coarse one, hot and sweet flavoured with my fermented habaneros and garlic in honey
    2. Another more dijon like with white wine vinegar

  12. So I am trying to get into fermenting, and am trying mustard as the first attempt. (using black mustard seeds and schezwan peppercorn (I like spicy stuff). though I am using a mix of water and raw apple cider vinegar. it is currently on day 5, sitting on top of a fridge(out of direct sunlight), not sure if it is an off smell or just from the vinegar, but it is pungent and the liquid is kind of a dark brown colour now, and no bubbling has occurred. is it still good? and if not, can it be salvaged?
