Before starting your fermentation journey, ensure you have all necessary items ready. You'll need fresh vegetables, non-iodized salt (such as kosher or sea salt), filtered water, and clean fermentation vessels. Glass jars work perfectly for beginners, but make sure they're thoroughly cleaned and sterilized. Choose vegetables that are fresh and free from blemishes or soft spots.

Wash your vegetables thoroughly and cut them into uniform sizes. For cabbage-based ferments like sauerkraut, shred or chop finely. For other vegetables like carrots, radishes, or cucumbers, slice them into consistent shapes. The key is uniformity, which ensures even fermentation throughout.

For most vegetable ferments, you'll need a 2-3% salt solution. For dry-salted ferments like sauerkraut, massage salt directly into the vegetables. For others, create a brine by dissolving 2-3 tablespoons of salt per quart of water. The salt creates an environment where beneficial bacteria can thrive while preventing harmful bacteria from growing.

Pack your prepared vegetables tightly into your clean jar, leaving 1-2 inches of headspace at the top. For dry-salted ferments, press down firmly to release natural juices. For brine ferments, pour the salt solution over the vegetables until completely covered. Ensure all vegetable matter is submerged under the brine to prevent mold growth.

Place your packed jar in a dark, room-temperature location (65-75°F is ideal). Use a weight or fermentation weight to keep vegetables submerged. Cover the jar with a loose lid or airlock system to allow gases to escape while preventing contamination. Place a tray under the jar to catch any overflow during fermentation.
