Wash the Mini Peppers (2.5 pound). You can also cut off the tops and take out the seeds if you'd like. (Optional)
Bring a large pot of water to a boil. Add the Mini Peppers and blanch for about 3 minutes. Using a slotted spoon, take the peppers out of the boiling water.
In 3 clean jars (1 quart each), add 2-3 peeled Garlic (9 clove) and Pickling Spice (1 1/2 tablespoon) (optional) to each.
Add the peppers to each jar.
In a medium saucepan, combine Water (4 1/2 cup), White Granulated Sugar (1 cup), Distilled White Vinegar (1 cup), Salt (2 1/2 tablespoon), Olive Oil (1/2 cup), and bring to a boil.
Pour the marinade over the peppers. Seal each jar. (If you want to store them for a longer time, sterilize the jars and lids in boiling water and put the filled jars into a water bath for 15 minutes.)
Let marinate for at least a few days before opening. Enjoy it anytime!
