Basically, a fermenting crock is a jar made of either stoneware or ceramic that you use to hold vegetables while they ferment.

If you want to use a fermenting crock, there are a couple of types to choose from and several features to consider.

Types of Fermenting Crocks

Open Crocks

If you are looking for a traditional fermenting crock, open crocks are the ones that you will find at your grandmother’s house or the antique shops. These old-fashioned crocks don’t have a lot of features and are very easy to clean and use. An open crock is basically a large crock that does not come with a top.

If you end up with your grandmother’s open crock or you buy one at the local antique store, make sure you check it over for cracks and other issues since you need a non-cracked pot for safe and proper fermenting.

Typically, open crocks will come in either five, three, or two-gallon sizes, which will allow you to easily place a whole vegetable inside it for fermenting. Once it is filled, you can use weights or anything long and heavy to hold the food down under the brine. You can then use a cloth or towel to cover the fermenting crock, or you could buy a new lid to use on your open crock.

Water-Sealed Crocks

Not always easy to find, a water-sealed crock is designed with a lip that holds water. These crocks come with a lid that can fit inside the lip preventing outside air from getting into the crock after you pour water into the lip creating a seal. It does allow carbon dioxide to escape that is created during the fermentation process. This type of crock also comes with weights that are made exactly for the crock to create a perfect barrier.

Considerations When Choosing a Fermenting Crock

When choosing a fermenting crock, it is important to think about how you will use the crockpot. Think about the types of fermented foods that you plan to make and what quantities you will be making. This will help you decide on the capacity you need, which is dependent on whether you will be making small or large batches. You want to make sure you have the right tool for the recipe you are making.

Keeping food submerged in liquid or brine is the key to fermenting foods. So you need to make sure you have enough headspace, which is where the weight object will sit to keep the food submerged. The headspace is important for the creations of safe fermented foods.

It’s also possible that the fermented foods you are making will swell, and you will need space for that process to happen. Plus, if you use the fermenting crocks for other types of projects, you will need to consider how you will use it and what the food requirements are that you want to ferment.

Many of these fermentation crocks are pretty large and can become very heavy when they are completely filled. Some people have a designated spot for their fermenting crock, but if you don’t have a specified area, you may want to think about getting a small fermenting crock. A small crock can be great for a fermenting project since it is easy to lift and move in comparison to larger ones.

If you happen to have a productive garden, you can ferment your vegetables in small batches. When you need to move your crock, you down want to drop it or hurt yourself by carrying the crock and all that food at once. However, it can be expensive to buy several small crocks instead of investing in just one large crock.

It can be worth the extra expense of these small crocks if you use you use them often. And the easy maneuverability of a small crock is a big benefit along with the ability to make many batches of various fermented foods at the same time. Plus, it’s important to remember that the fermentation process may take several months to complete.

Always make sure that no matter what size fermenting crock you choose, that the counter or table you put it on will be able to hold its weight when it’s full. Fluid can become very heavy, and you won’t want the table the crock is one to collapse and the crock shattering.

Many fermenting crocks don’t come with stones or lids. These two features have many benefits since you will have everything you need for the fermenting process, so you won’t have to go out and buy extra items to use during the fermenting process. Also, a lid will keep dust and other airborne objects from getting inside the crock. Having a crock with a lid designed for it that fits well is ideal. This makes it easy to use and set up.

It is always possible to buy stones or a lid for a crock that you found in your grandmother’s kitchen or the local antique store. If you do find a crock without a lid, you can always use a dinner plate that is close to the size of the crock’s opening along with a stone that can keep the food weighted down and submerged. The rock should be wrapped in cheesecloth or white cloth before placing it on the food to keep it submerged. Then, drape the white cloth or cheesecloth around the crock and cover it. This is a traditional method that has been used for decades that definitely works.

How to Use a Fermenting Crock

An easy way to start canning, using a fermenting crock is not a difficult process to learn. First things first, though, make sure you learn safe preservation and safe canning methods before you start. Then, find the right type of fermenting crocks for the recipes you plan to use. Always wash your vegetables and clean out the crocks before you get started.

Dependent on the food that you are fermenting, you may want to ferment them completely whole, sliced, or chopped. The type of brine solution that you use will also depend on the amount and type of vegetables you want to use.

It is helpful if you find a good fermentation recipe book. Find an easy one to start with, and then make sure to follow the measurements. After you have the vegetables and brine in the fermenting crock, you can then place the weights on top of the vegetables to make sure all the vegetables are submerged completely.

When you use a water-sealed crock, you will need to add water to the lip before placing the lid onto the top. The water that keeps the seal will eventually evaporate, so you will need to check on it each day to see if you need to add more water to maintain the seal. When you use an open crock, just use a dish towel over the top as a lid. Also make sure to check on it every day to look for weight-shifting, mold, or moisture problems.

After a few weeks, the food should be fermented and ready for you to eat. Depending on the level of tanginess that you like in your fermented food, you may want to leave it in the fermenting crock longer. Try and taste the food to test it out after about 12 to 14 days to see if you want it to go longer or if it’s done depending on your own personal preferences!

Using a fermenting crock can be a game-changer when it comes to family meals. Just make sure you have the right type of crock jar, features, and capacity that can handle the recipes you plan to make to ensure that you can make those delicious pickles, kimchi, and sauerkraut that your family loves.
