Hard-boil the eggs, then transfer to a bowl with cold water running over them to chill rapidly.
Once chilled, peel the eggs and set aside.
Add 1.5 cups of water (non-chlorinated!) to a large measuring cup. Stir in 1 Tbsp sea salt and 1/4 cup of starter until fully dissolved. Since I brew kombucha regularly, I like to use my kombucha starter. Set mixture aside.
Add the smashed garlic clove, bay leaf, fresh dill, and red pepper flakes to the quart mason jar. Then, add the peeled and hard-boiled eggs. Finally, top it with the brine, leaving 1-2" of headspace.
Add a fermentation weight to keep the eggs and add-ins from floating. If the contents are not completely covered, mix up a bit more brine (0.75 Tbsp salt to 1 cup of water) and add until completely submerged. Top with a fermentation lid, then place the jar in a cool, dark location (no warmer than 75F). A kitchen cupboard is great and where I keep my active ferments. Leave the jar to ferment at room temperature for 3 days. Once finished, you should notice that your brine has turned a bit cloudy. Excellent! Now, move the jar to the fridge to slow the fermentation process down, and enjoy your fermented eggs for up to 2 weeks.
