How to Make Fermented Snap Peas

Snap peas or sugar snap peas are one of those “blink and you’ll miss them” kind of produce. While they’re not quite as quickly there-and-gone as things like cherries, they do have a relatively short span of time in which they produce peas, and it’s fairly difficult to maintain that freshness of snap peas for any length of time. Thus the culinary experience of munching on sugar snap peas with roasted garlic hummus is a treat for my family for a few weeks mid-summer.

For long-term storage of snap peas, I shell them and put the peas in a bag and then in the freezer. While we no longer have the whole shell to eat, we at least have peas to keep us stocked throughout the year. (This year I’m attempting pea pod wine with the discard shells—look for a potential update on that in the winter!)

There’s a recipe for preserving snap peas I’ve been eyeing for a while and have finally tried—fermented snap peas.

Fermentation is the process of fostering an environment for beneficial bacteria to take hold in a food and choke out any bad bacteria. Fermented foods can then be stored for quite some time in the fridge, sometimes as long as several months, depending on the specific fermented food.

Fermented foods are loaded with probiotics and eating these foods can contribute to a healthy gut microbiome, which can have a broad impact on general health, including boosting the immune system. Fermented foods can also be easier to digest, which may be of benefit to some folks, and which can also increase nutrient absorption.

But, really, when you find a good recipe, fermented foods can be just darn delicious. Every week I make a batch of kombucha, which is a fermented tea-based beverage, and we drink it regularly.

So when I finally came across this recipe for fermented peas, it checked off a long list of things I was looking for—a new food preservation project, a way to preserve snap peas beyond their small window, and a delicious new food.

The science and art of fermentation

I’ve spoken before about how fermentation is both a science and an art, and it was me eventually coming to understand that symbiosis that led me understand the appeal of fermentation. The science is fairly basic—you use a saltwater brine (or just salt in the case of some foods like cabbage) to create an environment conducive to beneficial bacteria. These bacteria will thrive and outcompete the bad bacteria. That’s the science of it.

The art is where things can get a bit creative. You can flavour your fermented foods in a million different ways. For these fermented snap peas, I threw in some red pepper flakes and a heavy dash of Italian seasoning for some hot Italian snap peas. However, I could have instead thrown in some dill and peppercorns, or some sliced garlic, or the spices used in bread and butter pickles to make bread and butter snap peas.

How to ferment snap peas

The process is pretty simple and mostly requires patience.

You will need a fermentation vessel. I have a cool little Mason Tops kit that has a straight-sided jar, a glass weight, and an airlock for the top. You can also make do with any jar, a Ziploc bag filled with water as a weight, and a loose-fitting lid to act as a makeshift airlock. And, really, given how the peas are packed tightly and unlikely to float, you could probably skip the weight altogether.

Once you’ve got your fermentation vessel selected, start by putting any spices and seasonings in the bottom of the vessel. Then cram the peas in there. You’ll likely want to put them vertically so it’s easier to fill the narrow gaps with pea pods. (If you just dump the peas in, they’re not likely to be tightly packed and the brine you add won’t cover your peas.)

Unfortunately, I forgot to take any photos of this process for this blog. 🙃

In a bowl, combine water and salt (quantities listed in the recipe card below) and stir until all the salt has dissolved. This is your brine for fermenting. Pour the brine over the peas and ensure they are fully covered by brine. If not, you may need to push the peas further down or make more brine to top it up.

Put the weight on top of the peas, close the jar, and let sit in a cool, dark place to ferment. Fermentation will take several days. (If you’re using a regular lid and not one with a built-in airlock / air release, you will want to ensure the lid is loose-fitting to prevent gas buildup. Still, you may want to briefly and very quickly open the lid once a day to vent gasses.)

You’ll know it’s fermenting because of the bubbles that form and rise to the top. After several days, the peas should be ready. There’s no real test of readiness for fermented foods and it’s sort of a “how does it taste” assessment. Fermentation with saltwater creates a vinegar, so the peas should taste pickled, but the degree of “pickle-ness” is up to you. Once you determine it’s ready you can remove the weight and store the jar in the fridge. It should last several months.

How to use fermented snap peas

It was recently pointed out to me that while my recipes sound tasty, some of them would benefit from a section on how to use them—so welcome to a brand new feature to my recipe pages!

There are a variety of ways to use fermented snap peas:

  • When I do a BBQ or a dinner for a group of people, my appetizer is usually a baked brie with crackers, and whatever random pickles and preserves I have in my fridge. So this would go great paired with a baked brie, pickled beets, and sugar-fermented blueberries or Saskatoons.
  • Depending on how you flavour them, they would go great as a side of topping for dinner. I made spicy pickled snap peas with cayenne pepper and Italian seasoning, so it would go great paired with a stir-fry (the spice is more prominent than the Italian seasoning). If you’re eating fermented foods for the beneficial probiotic bacteria, you’ll likely want to add the peas when serving rather than cooking them in the stir fry, since the heat may kill the probiotic bacteria.
  • Fermented snap peas would also make a wonderful addition to a packed lunch or a bento box, as a vegetable side with a bit of a kick.

Fermentation 7 days

Equipment

  • Fermentation Vessel, with Weight and Airlock

Ingredients
  

  • 2 cups Water
  • 1 Tbsp Sea Salt
  • 2 cups Snap Peas
  • Seasonings, To Taste (see notes)

Instructions
 

  • Make the brine by combining water and salt, stirring until salt is dissolved.
  • Place seasonings in the bottom of the fermentation vessel. See notes for some ideas for seasonings.
  • Tightly pack peas into the fermentation vessel and cover with brine until peas are submerged. If peas are not submerged, you may need to pack them down tighter or add more brine. Putting the fermentation weight on top may push the peas down too.
  • Put the weight and lid on and store in a cool, dark place to allow peas to ferment. Check daily. You should see bubbles form after a few days; this is from fermentation.
  • Start tasting the peas after 5-7 days and then taste daily until desired fermentation has been reached. Once done, store peas in the fridge.

Notes

Spice options:
  • Spicy: 1 tsp red pepper flakes and 1tsp Italian seasoning
  • Garlicky: 1-2 garlic cloves, sliced, and 1 tsp peppercorns
  • Bread and Butter: 1 tsp mustard seeds, 1/4 tsp celery seeds, 1/4 tsp turmeric
Fermentation vessel:
If you don’t have a fermentation vessel you can use any large jar. In place of a weight, you can use a Ziplock bag filled with water or, if it fits, a small ramekin or other small dish. In place of an airlock lid, you can use a loose-fitting lid, but you may want to vent built-up gasses once per day, even if the lid is loose-fitting.
