It is best to wash and dry peppers in cold water.
Slice the stems of each pepper short, and pierce the sides three to four times.
Sliced peppers should be cut into pinwheels with the tops cut off and discarded.
The top of the jar should have about 1 inch of space between the peppers and the lid.
Cook the mixture over medium heat until the sugar and salt have dissolved completely.
Bay leaves, peppercorns, and chopped garlic should be added, and heat should be reduced to medium.
Five minutes is enough time to simmer.
Seal the pepper jars with lids after pouring the hot liquid into them. If the lids are too tight, the jars will be difficult to open after cooling.
Before placing jars in the refrigerator, allow them to cool.
It is best to marinate peppers for at least a week before using them. Peppers will have a stronger pickle flavor the longer they sit.
Keeping pepperoncini peppers in the refrigerator will preserve them for a number of months.
