I have had two jars filled with good food sitting on my counter for eleven months now and neither of them has gone bad. These jars were filled last September with some organic hot banana peppers I had purchased in season and wanted to preserve.

With very little effort and zero heating or freezing of the food, they practically preserved themselves with this easy fermented banana pepper sauce.

And now that I am getting ready to fill more jars with vegetables, salt, and water, it’s time for them to reach their final destination – fermented hot sauce!

Easy fermentation

Fermentation, as I go on and on about in my book, is probably the easiest, safest, healthiest way to put up your harvest. Not to mention the fact that fermentation makes the best, most nuanced hot sauce, in my opinion.

The aging of the banana peppers, the melding of the flavors, the lactic tang of the brine all come together in wonderful harmony.

Municipal tap water contains chlorine, which can inhibit fermentation, so be sure to use filtered or distilled water instead. A Berkey water filter provides clean water that’s free of toxins. Great for making your drinking water free of chemicals, but perfect for fermentation, too.

A fermented banana pepper recipe for preserving the heat

It’s almost too good to be true. But it’s not. It’s real and it’s easy, and it’s filled with enzymes and probiotics to boot. And don’t just toss the brine when you are done blending your hot sauce. There are plenty of uses for that too!

Banana Pepper Recipe: Fermented Hot Sauce

Yield: 12 servings
Prep Time: 5 minutes
Cook Time: 5 minutes
Total Time: 10 minutes

Make this spicy hot sauce from your garden fresh peppers for some probiotic -- spicy -- goodness in your diet!

Ingredients

  • scant quart of hot banana peppers, stems removed
  • 2 garlic cloves, peeled
  • 2.5 tablespoons sea salt
  • chlorine-free water as needed

Instructions

  1. Pack the peppers and garlic into a quart jar until 80% full. Add the salt to the peppers and then pour over the water to completely submerge the vegetables. Use a fermentation weight or homemade alternative to weigh the peppers down to below the level of the brine.
  2. Seal the jar with a canning lid and ring or an airlock and leave to ferment at room temperature for at least four weeks. During this time if you haven't used an airlock, you will need to "burp" your jar daily for the first two weeks in order to release the carbon dioxide produced by the fermentation process.
  3. After four weeks the peppers should be tangy and fully aged and fermented. They will keep for months in cold storage - a cellar or refrigerator - or even at room temperature.
  4. When you are ready to prepare the hot sauce, simply place the peppers, garlic, and 1/3 of the brine from the jar into a blender. Blend, adding more brine as needed to achieve the proper consistency. You can also blend it in a wide-mouth canning jar if you have an immersion blender. Taste and add salt or apple cider vinegar if you feel it needs some extra kick.
  5. The hot sauce should then keep for weeks refrigerated or on the table.

    What does airlock mean?

    • Kris Bordessa Sep 12, 2021 @ 8:45

      It’s a contraption that you put on the jar that allows air bubbles out but no air IN.

  • James Nov 2, 2020 @ 6:31

    Is it okay to cut the banana peppers in half in order to get more peppers in the jar?

    • Kris Bordessa Nov 2, 2020 @ 10:34

      Yes, of course!

  • James M Green Oct 31, 2020 @ 7:26

    Is that 2.5 tablespoons of sea salt or teaspoons?

    • Kris Bordessa Oct 31, 2020 @ 7:40

      Tablespoons. Thanks; I’ll spell that out right no.

      • James Nov 2, 2020 @ 6:28

        Thanks!

    do you dry your banana pepper seed for replanting? How?

  • Violette Jolicoeur Oct 19, 2020 @ 12:49

    Do you burp at all for the last 2 weeks?

    • Kris Bordessa Oct 26, 2020 @ 12:22

      If you’re not using a lid with an airlock or similar, it’s a good idea to burp, yes.

  • Ashleigh Geiger Jun 29, 2020 @ 15:39

    When you say to remove the stem, does this also mean removing all of the seeds? Or do you leave those? Excited to try this! Just started growing our own banana peppers, and wanted to make hot sauce with them.

    • Kris Bordessa Jul 1, 2020 @ 8:20

      You can remove or keep the seeds, as you like. The seeds/membranes are where the heat is, so this is a good way to “moderate” the spiciness.

  • Jessie Oct 18, 2019 @ 6:08

    What does it mean to “burp” the jar?

    • Kris Bordessa Oct 18, 2019 @ 14:44

      Just to open it up and allow any built up gasses to release. Easy, peasy.

  • Margaret Sep 24, 2018 @ 4:59

    My end of harvest garden yielded banana peppers and peppadews. I have a fermenting crock and was thinking of fermenting both together and then making a hot sauce. Your thougthts?

    • Kris Bordessa Oct 17, 2018 @ 9:39

      My thoughts: What are peppadews??

      • Farm Girl Oct 8, 2020 @ 14:50

        (Peppadew: a small, sweet pepper with a little heat. I think someone branded the name, as they are found in glass jars at stores).

  • Chris Bjorn Aug 31, 2018 @ 6:09

    Where are the bananas? The recipe says bananas, but I don’t see them used in the steps.

    • Kris Bordessa Sep 4, 2018 @ 17:56

      I can see the confusion, but this recipe calls for a variety of pepper called a BANANA PEPPER. No bananas. 🙂

  • Barb Aug 21, 2018 @ 2:45

    After the fermenting why can’t you blend all and bottle

    • Kris Bordessa Aug 22, 2018 @ 18:06

      You mean to make it shelf stable? I’m not comfortable saying that would be safe. Peppers are a low-acid food and not safe to water bath can. You’d need someone to check this recipe for the safety of that.

  • Shannon Aug 1, 2018 @ 15:10

    Can you give some examples of where you would use this sauce? We like spicy food but don’t often use hot sauce.

    • Kris Bordessa Aug 5, 2018 @ 16:37

      On tacos, stirred into chili, used as a seasoning when cooking things that need a little extra flavor.

  • Megan Apr 9, 2018 @ 20:12

    Good flavor, but a bit spicy!

  • Alena Sep 3, 2017 @ 10:55

    Just wondering if this would work with a salt alternative? I have someone who can not have the salt.

    • Kris Bordessa Sep 5, 2017 @ 7:01

      Fermenting may not be for you, then. Salt is key in the preservation process. Try pickling?

    • s w burk Oct 29, 2020 @ 13:19

      I was surprised to read on the label of the apple cider vinegar that it contained no salt. So my pepper sauce was sodium free. I had always thought vinegar contained a lot of salt.
