Put carrots in a quart size mason jar
Add the garlic and salt
Add starter of your choice (usually 1/4 cup whey OR 1/2 tsp culture starter)
Fill with room temperature filtered water. Leave one inch headspace.
Tighten lid and leave at room temperature 4-7 days. You will know they are done when the water gets cloudy and you may see some bubbling action. The mason jar lid may also be firm from the gases that are building up.
Transfer to refrigerator. They will keep for 6 months or more.
Enjoy your carrots!
