Start by thoroughly rinsing the fresh purslane under cool water to remove any dirt or debris. You can lay the rinsed purslane on a clean tea towel to dry or use a salad spinner to remove excess moisture. Set the prepared purslane aside.

In a medium saucepan, bring the filtered water to a boil. Once boiling, transfer the hot water into a glass, stainless steel, or ceramic bowl. Add the sea salt to the hot water and stir until it completely dissolves, creating the brine solution. Allow the brine to cool down to room temperature before using it in the fermentation process.

Now, prepare a clean pint-size, wide-mouth mason jar for fermentation. Add the rinsed and dried purslane, garlic cloves, pepper flakes, and grated ginger until they reach the shoulder of the jar. This ensures there's enough space for expansion during fermentation.

Carefully pour the cooled brine into the mason jar until it covers the purslane and other ingredients completely. Ensure that all the vegetables are submerged under the brine to prevent mold growth. Place the fermentation weight in side the jar to keep the ingredients submerged in the brine.

Attach a fermentation lid with an airlock on top of the mason jar. The airlock allows carbon dioxide produced during fermentation to escape, while preventing oxygen and contaminants from entering the jar. Place the jar in a cool spot, away from direct sunlight, to ferment for 7 to 10 days. During this time, the beneficial bacteria will work their magic, transforming the ingredients into flavorful, probiotic-rich fermented purslane.

Throughout the fermentation period, you may want to check on the progress of the flavor development. When the fermented purslane achieves a taste that suits your preferences, it's time to stop the fermentation process. Remove the fermentation lid and replace it with a standard mason jar lid and ring.

Finally, transfer the jar of fermented purslane with garlic and ginger to the refrigerator. The cold temperature will stop the fermentation process, preserving the flavors and probiotic content. Your homemade fermented purslane recipe is now ready to be enjoyed as a nutrient-packed addition to your meals!
