Now it's time to squeeze all of the vinegar out of the eggplant. You can do this by hand, or by squeezing it through a food mill. In my case, I'm using an Italian press specifically made to prepare this recipe.
Once you squeezed out all the vinegar, place, the eggplant into a bowl and now it's time to season it. With food safe gloves on, Break up the eggplant to loosen it. Add garlic cloves, peperoncino, oregano and oil. Mix well by hand, making sure that all of the eggplant is seasoned and coated.
Place into a sanitized 32 ounce mason jar. As you fill the jar press the eggplant down so that there are no air pockets. Once the jar is filled to 1 inch from the rim, place a piece of garlic, peperocino, and a sprinkle of oregano on top. Then pour oil on top just under the rim. Clean the rim with a piece of paper towel soaked in white vinegar. Placed the top on, but LOOSELY!
Do not seal the top for at least 3 to 5 days to allow the oil to settle. I usually place a paper towel underneath (in case of any spillage) and put it in a cool, dark place. After five days, I seal the top. I usually wait at least two weeks to consume the eggplant so that all the flavors can marry.
These pickled eggplants can last over a year. I have jars in my basement that are two years old and are perfectly fine. This pickling method ensures a long shelf life.
