Try Making Pickled Cauliflower with the Lacto-Fermentation Method 5

When cauliflower is in season, consider making pickled cauliflower using the lacto-fermentation method to preserve it. The pickled cauliflower florets are tasty and crunchy and packed with probiotics.

Fermentools sent me a kit to experiment with. I’ve found them to be an excellent and easy way for me to start fermenting successfully. This is a sponsored post.

My first attempt at lacto-fermentation?

It didn’t go so well. First, the whole idea of letting fresh food sit out on the counter until it ferments goes against everything I’ve ever been taught about cooking.

But beyond that, I was trying to cobble together a system that left me with a moldy, uh, buggy mess that ended up in the compost.

It’s a simple thing, but it’s essential that the food you’re trying to ferment remain completely submerged under the brine. Mine did not. Thus, the big ole fat fail.

That was two or three years ago.pickled cauliflower in a swing top jar

While I continued to make my kimchi, I simply hadn’t delved into any more attempts at lacto-fermentation. Until now.

Let me tell you: The little glass weights that come as part of every Fermentools kit? They are brilliant.

They fit perfectly into a wide mouth jar to hold down the ingredients while they transform into lacto-fermented goodness.

No more finagling some sort of weight that might (maybe? kind of?) work!

So, what to ferment??

You know those jars of pickled vegetables that include carrots and celery and pickled cauliflower?

The carrots and celery are completely taking up prime real estate that could otherwise be used by pickled cauliflower. So when I decided to try this whole lacto-fermentation business again, I decided to start with my favorite: Cauliflower.

It took me 25 minutes, start to finish, to assemble three pints of cauliflower — and that included tracking down a couple of wide mouth jars (still packed from our move) and washing them, unpacking my kit from Fermentools, plus a quick jaunt to the garden to grab a couple of peppers.

Someone more organized than me could probably have done it in ten.

Heads up: Municipal tap water contains chlorine, which can inhibit fermentation, so be sure to use spring or distilled water instead.

This pickled cauliflower recipe uses the lacto-fermentation method of preservation. 

Course: Salad
Cuisine: American
Servings: 15
Calories: 11 kcal
Author: Kris Bordessa
  • 4 cups water see recipe notes
  • 2 tablespoons sea salt or pickling salt
  • 1 head of cauliflower
  • hot peppers
  • cloves garlic
  1. Mix water and salt to make brine; set aside. Place one pepper and one garlic clove in each jar. 

  2. Cut cauliflower into bite sized pieces and divide between jars, then divide brine over cauliflower to cover. (If you don’t have quite enough brine, you can add water to top off each jar.)

  3. Place glass weight on top of the cauliflower to assure it’s submerged. Set Fermentools rubber ring and lid in place, screw on a band (from your stash), then place the airlock into the hole.
  4. Set in an out of the way place to ferment for 3-5 days. (There’s potential for these to overflow a little, so set fermenting jars in a pan of some sort to catch drips.) 

  5. Test the cauliflower after a few days; if you’re happy with the level of fermentation, replace the Fermentools lid with a regular canning lid and refrigerate. Not quite ready? Leave out on the counter for another day or two. Be sure to use a clean utensil to remove cauliflower — using fingers could contaminate the brine.

Recipe Notes

Water: Municipal tap water contains chlorine, which can inhibit fermentation. Use spring or distilled water instead. Salt: Salt with iodine or anti-caking agents can inhibit fermentation. Brine: Four cups of brine is enough for approximately three pint jars of cauliflower.

When cauliflower is in season, consider making pickled cauliflower using the lacto-fermentation method to preserve it. These pickled cauliflower florets are tasty and crunchy and packed with probiotics. Plus? There's no cooking involved and it's *easy. #fermenting #pickles #preservation

    Your cauliflower looks amazing, my fav vegetable.
    One of my jars of fermented vegetables, distilled water, sea salt, cauliflower, broccoli, garlic, and carrots has a white layer and ring around the top. I started them 1 month ago. They stay submerged. Any idea what the white ring is?

      Ferments can get a thin layer of white yeast on top of them. Scrape it off and give the jar a sniff; if it doesn’t smell objectionable, it’s likely fine. If the top gets pink, green, or black, you’ll want to toss it.

    I just made pickles using this method and they were ready in two days, I live in AZ and it is warmer here. I am going to try this next since I am pretty sure the pickles won’t last long. They are very good! Someone suggested adding a teaspoon of vinegar to prevent the yeast growth. I did it and it worked do you know if this can be done with the cauliflower?

    • Kris Bordessa Post author

      I’ve never added vinegar to a ferment, and the yeast is a byproduct of fermentation. Not sure I’d want to eliminate it.
