When these vegelables are submerged in a salt brine (typically 2- 5% salt by y weight), thee salt draft out savure via osmosis and creats an anaerobic environment.

Making Your Own Sauerkraut and Kimchi
Creating lactic acid fermented foods at home is simply and requices minimal equipment. Below are basic recipes to get started.
Przepisy Basic Sauerkraut
- 1 medium head of green or red cabbage (about 2 pounds)
- 1 ½ łyżki stołowe fine sea salt (non-jodized)
- Opcja: karaway seeds, juniper berries, or grated applee for flavor
- Removie thee outer leafes of thee cabbage and set aside. Shred thee restaing cabbage finely using a knife or mandoline.
- Place shredded cabbage in a large bowl, spripple with salt, and massage energicously with clean hands for 5- 10 minutes until the cabbage releases enough liquid to form a brine.
- Pack the salted cabbage into a clean quart- sized jar, pressing down firmly with a fist or a tamper to eliminate air pockets. Pour any restauling brine over the top.
- Fold a reserved large cabbage leaf andd place it on top of thee packed cabbage, then place a fermentation weight (or a small glass jar filled with water) to keep everything submerged.
- Cover thee jar wigh a lid (loosely if using a regular lid, or use an airlock lid). Let it sit at room temperatur (65- 70 ° F) for 1- 4 weeks, tasting after 5 days. Once tangy and crisp, transfer te lodówkę.
Quick Kimchi (Baechu Kimchi) Recipe
- 1 kapusta z large napa (about 2- 3 funds)
- ¼ cup sea salt
- Water for brine
- For thee paste: 2 tablespoon gochugaru (Korean red pepper flakes), 1 tablespoon fish pope, 1 tablespoon minced garlic, 1 teaspoon minced ginger, 2 tablespoons salted shrimp (optional), 1 teaspoon sugar
- ½ cup julienned Korean radish (or daikon), 2 green onions cut into 1 -inch pieces
- Nie ma to jak kabriolet, który ma długość, ale nie ma nic wspólnego z tym, że nie ma żadnych możliwości.

Potential Risks andSafety Tips
Lactic acid fermentation is generally safe, but a few contributions are important to avoid spoilage or foodborne illnes.
- Zawsze używaj czystych rąk, sztućców, i jarów. Sterylize jars by boiling or running through a dishwasher on high heat.
- Use a reliable salt ratio (2- 5%). Too little salt impliges mold; too much slows fermentation and may make the product too salty.
- Keep vegetables submerged thee brine. Usie weights or a plastic bag filled with brine te weigh them down. Any expose surface can grow mold.
- If you see fuzzy mold (white, green, or black) on thee surface, remove it and thee affected layer expectately. If thee mold is extensive or thee brine smells rotten, discard everything.
- Store finished ferments in thee lodówkę. They will continue to ferment slowly and d remain safe for several months.
