The Art of Fermentation

Fermentation is an age-old technique used to preserve and enhance the flavors of various foods. In the case of sauerkraut, it involves naturally fermenting cabbage, which results in the creation of lactic acid by beneficial bacteria. This process not only preserves the cabbage but also provides the distinctive tanginess that sauerkraut is known for.

Adding apples and onions to the mix adds a unique layer of flavor, transforming your sauerkraut into a sweet and savory delight. The combination of traditional cabbage with the subtle sweetness of apples and the savory touch of onions creates a sauerkraut that is as unique as it is delicious.

Ingredients You’ll Need

Before you embark on this sauerkraut-making journey, gather the following ingredients:

  • 1 medium-sized green cabbage
  • 2-3 medium-sized apples (choose a sweet variety, such as Fuji or Honeycrisp)
  • 2-3 large onions (yellow or red onions work well)
  • 2 tablespoons of sea salt (non-iodized)
  • A clean, sterilized quart-sized glass jar

Creating Apple Onion Sauerkraut

Let’s dive into the steps of crafting this delectable Apple Onion Sauerkraut:

1. Prepare the Ingredients

To begin crafting your delectable Apple Onion Sauerkraut, gather the necessary ingredients. Start by washing the green cabbage, apples, and onions thoroughly under cold running water. Afterward, pat them dry with a clean kitchen towel. Next, remove the tough outer leaves of the cabbage and set them aside for later use. Using a sharp knife or a food processor with a shredding attachment, finely shred the cabbage, apples, and onions.

The goal is to create thin, uniform strips that ensure even fermentation and provide an appealing texture to your sauerkraut. With your ingredients prepared, you’re ready to embark on the journey of infusing the earthy sweetness of apples and the savory aroma of onions into your sauerkraut, creating a unique and delightful twist on this traditional favorite.

2. Combine the Ingredients

With your finely shredded cabbage, apples, and onions ready, it’s time to combine these key ingredients for your Apple Onion Sauerkraut. In a spacious mixing bowl, place the shredded mixture, and evenly sprinkle the sea salt over it. The salt plays a vital role in drawing out moisture from the ingredients, facilitating the formation of the brine essential for the fermentation process.

As you gently mix these elements together, you’re setting the stage for the unique flavor journey your sauerkraut will embark on. The traditional tang of cabbage combines with the subtle sweetness of apples and the savory touch of onions, creating a sauerkraut that’s a harmonious blend of flavors, sure to tickle your taste buds and leave you wanting more.

3. Massage and Squeeze

The next step in crafting your Apple Onion Sauerkraut is a hands-on process that involves massaging and squeezing the shredded mixture. This manual interaction is critical for breaking down the cell walls of the ingredients and encouraging them to release their natural juices. As you gently massage and squeeze the cabbage, apples, and onions, you’ll notice the mixture gradually softening and liquid starting to accumulate in the bowl.

This liquid, combined with the sea salt, is fundamental in creating the brine required for the fermentation process. Spending 5-10 minutes massaging and squeezing ensures that the brine forms effectively, setting the foundation for the delightful sweet and savory sauerkraut that’s soon to come.

4. Pack Tightly

After massaging and squeezing the cabbage, apples, and onions to create the essential brine, it’s time to move on to the next step in crafting your Apple Onion Sauerkraut. Transfer the mixture into your clean, sterilized quart-sized glass jar. As you fill the jar, be sure to pack the ingredients down firmly, eliminating any air pockets. This tight packing is essential for ensuring that the cabbage, apples, and onions are fully submerged in the brine.

The brine should entirely cover the ingredients, creating a protective environment for the fermentation process to work its magic. The visual symphony of colors – the vibrant green cabbage, the earthy red onions, and the golden apples – is the first hint of the delicious sauerkraut that’s in the making.

5. Use Reserved Cabbage Leaves

Don’t forget the tough outer leaves of the cabbage that you set aside earlier in the process. These reserved cabbage leaves play a crucial role in ensuring the success of your Apple Onion Sauerkraut. Place one or two of these leaves on top of the tightly packed mixture in the glass jar. By doing so, you create a natural barrier that helps keep the shredded cabbage, apples, and onions submerged beneath the brine.

This is a vital step to prevent exposure to air, which can lead to spoilage or mold growth. The cabbage leaves serve as a protective layer, preserving the integrity of your sauerkraut and allowing it to develop its unique sweet and savory flavors during the fermentation process.

6. Weight It Down

To ensure your Apple Onion Sauerkraut remains submerged in the brine during the fermentation process, it’s crucial to use a weight. You have a couple of options for this. A clean, small glass jar filled with water or a purpose-made fermentation weight both work effectively. Place the weight on top of the cabbage leaves you previously positioned on the sauerkraut. The weight exerts gentle pressure, ensuring that the shredded cabbage, apples, and onions stay beneath the surface of the brine.

This step is crucial in preventing exposure to air, which can lead to spoilage or undesirable microbial growth. The weight not only safeguards the sauerkraut but also helps create a favorable environment for the beneficial bacteria to work their magic, transforming your mixture into a sweet and savory delight.


7. Seal the Jar

With your Apple Onion Sauerkraut meticulously prepared, packed, and weighted down, it’s time to seal the quart-sized glass jar. You have a couple of options for the type of lid to use. You can opt for a fermentation airlock lid or simply use a regular jar lid, ensuring it’s only loosely tightened. The purpose of this step is to allow the carbon dioxide produced during fermentation to escape while preventing contaminants from entering the jar.

Alternatively, you can choose to “burp” the jar daily by slightly loosening the lid to release any built-up gas. This sealing process marks the beginning of the fermentation journey that will infuse your sauerkraut with sweet and savory notes, offering a unique flavor profile that’s sure to delight your palate.

8. Ferment

With your Apple Onion Sauerkraut sealed in its jar, it’s time for the magic to happen. Place the jar in a cool, dark spot with an ideal temperature range between 60-70°F (15-21°C). Over the next several days, you’ll notice small bubbles forming within the jar. These bubbles are an exciting sign that the beneficial bacteria are hard at work, converting the natural sugars in the cabbage, apples, and onions into lactic acid.

This transformation not only preserves your sauerkraut but also imbues it with a delightful sweet and savory flavor. The fermentation process may take varying lengths of time, depending on your taste preference, so monitor your sauerkraut and prepare to be amazed by the unique and delectable results that await.

9. Taste and Adjust

After several days of fermentation, it’s time to sample your Apple Onion Sauerkraut and assess its tanginess. Taste it to gauge whether it has reached your desired level of flavor. Fermentation time can vary according to personal preference, so it’s crucial to check periodically. When it achieves the balance of sweet and savory flavors that you find most appealing, seal the jar tightly and transfer it to the refrigerator.

This refrigeration step slows down the fermentation process, ensuring your sauerkraut retains its unique taste profile. Your patience and attention to detail have led you to a delicious, homemade sauerkraut that blends the sweetness of apples and the savory charm of onions with the traditional tang of cabbage. Your Apple Onion Sauerkraut is now ready to enhance a variety of dishes and elevate your culinary creations. Enjoy the sweet and savory twist you’ve crafted with your own hands.

10. Store and Enjoy

With your Apple Onion Sauerkraut at the perfect level of tanginess, it’s time to store and savor your creation. Properly stored in the refrigerator, your sauerkraut can last for several months. The cool temperature will slow down the fermentation process, allowing the flavors to continue to develop and mature. Over time, you may notice subtle changes in taste, with the sweet and savory notes of apples and onions becoming more pronounced.

You can use your sauerkraut to enhance a wide array of dishes, from sandwiches and salads to hot dogs and savory mains. Get creative and explore various culinary combinations to enjoy its vibrant and unique flavor. Your homemade Apple Onion Sauerkraut is not only a delightful twist on tradition but also a testament to your culinary prowess. Savor the results of your efforts and relish the delicious addition you’ve brought to your kitchen.
