Aren’t pickles fun? They’re such a great way to preserve the harvest, plus making pickles gives you a chance to experiment with flavor combinations. Not to mention, pickles of all kinds make great snacks and accompaniments to meals.
Here we explore two very different ways to turn vegetables into pickles: lacto-fermentation and vinegar pickling (with a hot-water bath to preserve them). We don’t stop with vegetables though, read on to discover some of the unconventional morsels we like to throw in the pickle jar. There are lots of other ways to preserve the harvest, too, including root-cellaring and other non-electric methods.
Learn how to lacto-ferment in a step-by-step video-based class with master microbialist, Marissa Percocco in our Online Vegetable Fermentation Class.
What is pickling?
According to the Merriam-Webster dictionary, a pickle is “an article of food that has been preserved in brine or in vinegar; specifically : a cucumber that has been so preserved.” The origin of the word pickle is a little murky. In fact, it’s been postulated that it may be the last name of medieval Dutch fisherman who came up with the process. But pickling has been around much longer than that. According to an article from PBS, people were pickling cucumbers in the Tigris Valley in 2030 BC! Wherever there are seasons of bounty and of lean times, human beings have made pickles to help get them through.
What gets pickled?
Vegetables are by no means the only foods that get the pickle treatment. However, cucumber pickles and sauerkraut (lacto-fermented cabbage) may be the most popular. Both limes and green mangos are very common fruit pickles in India. Meat can be pickled too. For example, corned beef, pickled pig’s feet, and herring in wine sauce are examples of this. Even whole, hard-boiled eggs can find themselves floating in brine. Feta is a common kind of cheese that gets pickled in its own tangy whey, plus generous salt.

Lacto-fermentation vs. vinegar pickling
Using vinegar or salty brine are two of the most common ways to pickle.
In the case of salty brine, beneficial bacteria eat the sugars in the vegetables on their way to becoming pickles. As a result, lactic acid is released, turning the saltwater into an acidic solution; this process is called lacto-fermentation. For vinegar pickles, salt is almost always added too. So, what’s the difference between these two sour-salty solutions?
The presence of probiotics, or beneficial bacteria, is the main difference between lacto-fermentation and vinegar pickling. Lacto-fermented pickles are cultured, and full of priobiotics. Additionally, sealing vinegar pickles in a hot water bath is very common. When we do this, we cook both the pickles and the brine. As a result, we can store them at room temperature in their sealed jars for a long time without spoiling. Lacto-fermented pickles are not cooked, and can only be stored for long periods of time at low temperatures (like in a refrigerator or root cellar). Check out our infographic below for a comparison of some of the pros and cons of these two ways to pickle.
Great pickle recipes
Pickle diversity is as vast as human culture. Here are two basic recipes to get started, from two awesome books on food preservation. There are tons of other pickling books out there. We especially encourage you to explore recipes for pickles and preserves from India, Ukraine, Germany and Japan. Those are among the pickle loving cultures who have perfected many piquant delicacies.
Sour Beets (lacto-fermented)

- Place a weight atop the beets and make sure all of them are submerged
- Cover with a cloth to exclude bugs
- Check after a few days, it will get more sour over time and be “done” in 1-4 weeks depending on temperatures
- When you deem it done, pack into clean jars and store in the refrigerator.
