We all have moments where we crave certain foods that we ate growing up. As the daughter of a Korean mother and a Polish father, I got to experience elements of these two very different food cultures right inside our home. When my mom cooked for the family, she would make Korean soups, marinated meats, and pickled vegetables that we would eat with rice. When my dad cooked, he would serve kielbasa with sauerkraut and rustic bread. Although at first glance these cuisines seem to have very little in common, there was one unique ingredient that tied them together, and that was fermented cabbage. What exactly is fermented cabbage? During the process of food fermentation, vegetables are typically soaked in salt water or their own juices, allowing for certain bacteria to grow. These friendly bacteria are known as lactic acid bacteria because they feed on the natural sugars of the vegetables to produce lactic acid. This creates the characteristic tangy flavor that many fermented foods are known for (1). Both Korean and Polish cuisines utilize fermented cabbage in a variety of dishes. The Korean version, kimchi, is typically made from Napa cabbage that has been cut into large chunks and is seasoned with chili pepper, garlic, scallions, and fish sauce. Kimchi is often eaten as a side dish with rice. A common staple in Polish cuisine is sauerkraut, which is made from finely shredded green cabbage soaked in salt brine. Sauerkraut is fermented at a higher temperature than kimchi and has a higher acidity and lower salt content (2). It is commonly eaten with pork or sausage, in stews, or as a filling in traditional Polish dumplings called pierogiâ€TMs. Although it may sound unappetizing to allow bacteria to grow in our foods, fermentation was actually one of the first methods used for safe food preservation centuries ago (3). The lactic acid that is produced during fermentation kills disease-causing bacteria that would normally cause food to spoil over time. The use of salt also acts as preservative and prevents the growth of harmful bacteria during this process. Further driving our this “fermentation frenzy” in our food culture is that the bacteria found in fermented foods are considered probiotics. These “good” bacteria and are similar to those found naturally in your gut that help with overall health and digestion. You probably have heard of these friendly bugs in cultured dairy products such as yogurt. Probiotics that occur naturally in foods are absorbed by the body much more effectively than probiotics in supplemental form. Another great reason to include fermented vegetables in your diet (4)! Although fermented foods are often high in sodium, there are low-sodium versions available that can be enjoyed in moderation. Kimchi is a little harder to find and is typically sold at Asian markets, but can easily be made at home. Check out the following Reduced Sodium Kimchi recipe and serve it with rice or mix it in with a slaw for an added punch of flavor. Reduced Sodium Kimchi
2 tablespoons kosher salt
2 ½ tablespoons red chili pepper flakes ¼ cup very thinly sliced onion
2 teaspoons minced garlic
1 teaspoon grated ginger
1. Cut cabbage vertically into 8 wedges. Cut each wedge crosswise into 2-by-1-inch pieces. Place cabbage in large stainless steel or glass bowl. Add salt. Sliding hands down sides of bowl, lift and squeeze handfuls of cabbage, pile them on top and repeat until cabbage is wet and slightly wilted, 3-4 minutes. Set aside for 50 minutes. 2. Transfer cabbage to large colander and place under cold running water for 1 minute, stirring cabbage to rinse thoroughly. Drain cabbage for 30 minutes. Transfer cabbage to large bowl and add scallions, chili flakes, and onion. On a cutting board, combine garlic, ginger, and sugar. Using the side of heavy knife, press and smear, then scrape together and chop mixture. Repeat 3-4 times to make a coarse paste. Let paste stand for 15 minutes. Add paste to cabbage mixture and use a sturdy fork to mix until contents of bowl are well combined. 3. Pack the mixture into 1-quart glass canning jar, leaving 1 ½-inch space at top. There will be some small air bubbles in jar. Add ¼ cup water to bowl, swirl to collect any remaining seasoning, then pour liquid into jar. Screw on the lid, set the jar in a bowl, and let it stand at room temperature (65-70°F) for 3 days. (Some liquid may come out.) 4. After 3 days, when you open jar, top of kimchi may look foamy or have little bubbles; this indicates fermentation has taken place. In refrigerator, kimchi will keep several months, continuing to ferment slowly. Nutrition Facts: (per ¼ cup)
