Wash your pears in water.
Place them in the jar.
Add your ginger, sugar, and kombucha starter tea.
Top off jar to completely cover the pears with water. (See notes.)
Top with a ferment spring and lid (or anything you have that will keep the pears on the top submerged in the brine and bugs out of your jar).
Place your jar on a plate, to catch the brine as it bubbles out in the days ahead, as the lactic acid builds up.
After about 3-5 days, remove the fermenting spring and lid, replace with a standard lid, and place the jar in your refrigerator.
