The art of fermented foods goes back in history as a way of preserving your harvests, but there's much more to it than just preservation; there are health benefits too. We've been fortunate to uncover the science behind fermented foods and truly understand their impact on our gut. In this blog post, I'm going to explain some of the health benefits, and different types of fermented foods, touch on the science behind fermented foods, and show you that it's possible to grow the ingredients to create your ferments. Maybe I'll even throw in a super simple recipe that I like to use for some of my garden harvests.
The Health Benefits of Fermented Foods
Let's check out the amazing health benefits that come with including fermented foods in your diet. These foods aren't just delicious; they're packed with goodness that can do wonders for your well-being! Fermented foods play a crucial role in supporting gut health by replenishing and diversifying the beneficial bacteria in your digestive system. They're also great for giving your immune system a boost, helping your body fight off pesky bugs and stay resilient. Also, fermented foods are like digestive superheroes, aiding in the breakdown and absorption of nutrients to keep you feeling great. And guess what? Research even suggests that enjoying fermented foods could have a positive impact on your mood and mental health.

Different Types of Fermented Foods:
There are many choices when deciding on which fermented food you want to enjoy, some of the more common ones are:
1. Yogurt: I absolutely love yogurt, it is perfect for breakfast bowls, smoothies, or as a tangy topping for granola, just make sure you are watching the sugar content of your store-bought yogurts. This is simple to make at home, you should give it a try.
2. Sauerkraut: This crunchy delight adds a tangy punch to sandwiches, salads, or as a zesty side dish to complement your main course. I like adding a spoonful to just about all of my dishes as a condiment. Just to add a bit of probiotics to all of my meals.
3. Kimchi: Bursting with spicy flavor, kimchi is a staple in Korean cuisine, ideal for adding a kick to rice bowls, stir-fries, or as a vibrant topping for tacos. Kimchi is a great side to use just like sauerkraut.
4. Kefir: Rich in probiotics, kefir makes for a tasty drink on its own or can be used as a base for creamy salad dressings and dips.
5. Miso: A savory umami bomb, miso adds depth of flavor to soups, marinades, and glazes for roasted vegetables or tofu. I must say that miso is not my favorite, but I do use it from time to time to get diversity in my ferments.
6. Tempeh: With its nutty taste and firm texture, tempeh shines in stir-fries, salads, or marinated and grilled for a hearty plant-based protein option.
These fermented foods offer a wide array of flavors and textures, making them great additions to your meals.
The Art and Science of Fermentation:
Oh, the magic behind the art and science of fermentation! This fascinating process involves the work of tiny but mighty microorganisms like bacteria and yeast, which transform ordinary ingredients into flavorful and nutrient-rich foods.
First, let's talk about these microbial superheroes. Bacteria and yeast are the unsung heroes of fermentation, breaking down sugars and other compounds in our ingredients. They create a range of beneficial byproducts, from probiotics that support our gut health to enzymes that aid in digestion.
Now, let's check out the different methods of fermentation.
Wild Fermentation:
This method relies on the naturally occurring microorganisms present in the environment and on the food itself. It's a more spontaneous process, often resulting in unique flavors and textures. To try wild fermentation, just allow your ingredients to sit out and let nature work its magic!
Are wild fermentation safe:
Wild fermentation can be safe, but it needs close attention to detail and some knowledge of the process. The key to successful wild fermentation is making the right conditions for beneficial microbes to thrive and not allowing the growth of harmful bacteria. Here are some things to ensure safety when creating your wild fermentation:
1. Cleanliness: While wild fermentation depends on natural microorganisms, it's important to start with clean and sanitized equipment. This helps prevent harmful bacteria from taking over during the fermentation process.
2. Quality Ingredients: Use fresh, high-quality ingredients for your wild ferments. Fresh fruits, vegetables, and herbs from your own garden are a great source and will have a better chance of hosting beneficial microbes.
3. Salt and Brine: Salt is often used in wild fermentation to create an environment that is unfriendly to harmful bacteria. The salt also helps draw out moisture from the ingredients, creating a brine that also deters harmful microbes.
4. Observation: Keep a close eye on your ferments. Look for signs of mold, off-putting odors, or any other signs that something may be wrong. If in doubt, it's best to throw it out!
What foods can I ferment?
1. Vegetables: Cabbage is a classic choice for wild fermentation, as seen in sauerkraut. Other vegetables like carrots, cucumbers (for pickles), radishes, and beets can also be fermented using wild methods.
2. Fruits: Berries, apples, pears, and stone fruits like plums and peaches can be fermented to create tangy fruit ferments. These can be used as toppings for desserts, added to salads, or enjoyed on their own.
3. Herbs and Spices: Herbs such as dill, cilantro, and mint can be added to vegetable ferments for added flavor. Spices like coriander seeds, mustard seeds, and peppercorns are also common.
4. Grains: Wild fermentation is also used in fermenting grains to create products like sourdough
bread. The wild yeast in the air helps leaven the bread and create its distinctive tangy flavor.
Remember, when trying wild fermentation, it's important to start small and be patient. It may take some trial and error to find the right balance of flavors and textures. With good care and attention, you can make tasty and safe wild ferments right in your kitchen!
Lacto-Fermentation:
In this method, we harness the power of lactic acid bacteria to create tangy and sour flavors. This is the process behind classics like sauerkraut and pickles. To get started with lacto-fermentation, all you need is your vegetable of choice, salt, and a clean container.
What is the difference between lacto and wild fermentation if they both require salt:
Wild fermentation and lactic fermentation are both methods of fermenting foods, but they differ in the way they harness microbial activity and the exact types of microbes involved.
In wild fermentation, the process depends on the naturally occurring microorganisms present in the environment and on the surface of the food itself. This method is more spontaneous and uncontrolled compared to other forms of fermentation. Wild fermentation does not involve the intentional addition of a specific starter culture.
Salt is often used in wild fermentation to create an environment that is more favorable to beneficial microbes and less hospitable to harmful bacteria. The salt helps draw out moisture from the ingredients, making a brine that supplies an ideal environment for fermentation. The natural microbes present, such as wild yeast and lactic acid bacteria, begin to multiply and ferment the sugars in the food.
The result of wild fermentation can vary widely depending on the specific microorganisms present in the environment. This method often produces unique flavors and textures in the final creations.
Lacto-fermentation, on the other hand, is a more controlled method of fermentation that involves the intentional addition of a specific type of bacteria called lactic acid bacteria. This group of bacteria, which includes species such as Lactobacillus and Pediococcus, is responsible for transforming sugars into lactic acid.
In lacto-fermentation, salt is also used to create an environment that favors the growth of lactic acid bacteria while inhibiting the growth of harmful bacteria. The salt helps draw out moisture from the ingredients, creating a brine similar to wild fermentation.
The key difference with lacto-fermentation is that the specific lactic acid bacteria added to the fermenting food overpower the fermentation process. These bacteria produce lactic acid as a byproduct, which not only preserves the food but also creates the tangy and sour flavors part of lacto-fermented foods.
While both wild fermentation and lacto-fermentation involve the use of salt, the primary difference lies in the intentional introduction of specific microbes in lacto-fermentation compared to the reliance on naturally occurring microbes in wild fermentation. Both methods can produce tasty and nutritious fermented foods, each with its unique characteristics.
Alcoholic Fermentation:
This process, as the name suggests, results in the production of alcohol. It's commonly used in brewing beer, fermenting wine, and even making kombucha. The yeast feasts on sugars, producing alcohol and carbon dioxide as byproducts.
Some practical tips for successful fermentation at home are to make sure you are using clean and sanitized equipment to prevent unwanted bacteria, maintain the right temperature, think cool, dark place away from the direct sun, experiment with flavors add herbs and spices and by all means, don't forget to burp your ferment. Yes, it needs to be burped to release built-up gases, they do make self-burping lids which I highly suggest purchasing because if you like me you will likely forget a ferment or two.
Fermentation is as much an art as it is a science, and there's plenty of room for creativity in your ferments. So, don't get worried, and overthink it, just experiment and find that homemade ferment that you and your gut will love.
Growing Your Ingredients for Fermentation:
There's something truly awesome about growing your own produce, especially when it comes to creating tasty ferments. Gardening for fermentation offers a ton of benefits, from the joy of harvesting fresh, organic ingredients right from your backyard to the pleasure of knowing exactly where your food comes from. Not to mention the possible cost savings that come with growing your veggies and herbs!
If you are already growing a great garden, look around and see all the possible ferments you can do. Let's start with the all-knowing cabbage, the star of sauerkraut, this crop thrives in cool weather and can be easily grown in gardens. Cucumbers are another excellent choice, perfect for making pickles with just a few simple ingredients. And let's not forget about herbs, those aromatic beauties add depth and flavor to ferments. But there are vegetables beyond just the basic ones I have mentioned. Do not be afraid to explore different types of ferments and add in those extra veggies that you have on hand or try a new mixture. Below is an idea for a garden mixture perfect for fermentation. It is great also when your vegetables are just starting to produce so you have enough for fresh eating, maybe not enough for preserving. I just throw it all into a ferment and see what I get.
Fermented Garden Mix Recipe:
Ingredients:
- 2 large onions, thinly sliced
- 1 head of garlic, cloves peeled and smashed
- 1 large carrot, peeled and thinly sliced
- 1 small head of cauliflower, cut into small florets
- 1 small red bell pepper, sliced into strips
- 2 tablespoons sea salt (non-iodized)
- 1 teaspoon whole black peppercorns
- 1 teaspoon mustard seeds
- 1 teaspoon coriander seeds
- 2-3 sprigs fresh thyme (or 1 teaspoon dried thyme)
- Filtered water
Instructions:
1. In a large mixing bowl, combine the sliced onions, smashed garlic cloves, carrot slices, cauliflower florets, and red bell pepper strips.
2. In a separate small bowl, mix the sea salt, black peppercorns, mustard seeds, coriander seeds, and thyme.
3. Sprinkle the salt and spice mixture over the vegetables in the mixing bowl.
4. Using clean hands, massage the salt and spices into the vegetables for about 5-10 minutes. This will help release the juices from the vegetables.
5. Transfer the vegetable mixture and any collected juices into a clean, quart-sized glass jar.
6. Press down on the vegetables to pack them tightly into the jar, making sure they are submerged in their juices. If needed, add a little filtered water to cover the vegetables.
7. Place a clean weight on top of the vegetables to keep them submerged under the liquid.
8. Loosely cover the jar with a lid or a clean cloth secured with a rubber band, (I prefer the lids that come in this fermenting kit)
9. Place the jar in a cool, dark place (such as a pantry or cupboard) and let it ferment for about 1-2 weeks. Check the garden mix every few days and press down the vegetables if they rise above the liquid.
10. Once the garden mix reaches your desired level of tanginess and flavor, remove the weight and secure the jar with a lid. Refrigerate the garden mix to slow down the fermentation process.
11. Try your homemade Fermented Garden Mix as a tasty addition to salads, sandwiches, and wraps, or as a tasty side dish!
