Prepare the jars

This is a very important step which most people tend to overlook. You must wash and sanitize your jars. If your dishwasher has a sanitize cycle then use it. Otherwise put the jars and lids in boiling water. Take out the lids after 5 minutes and the jars after 10 minutes. Put them aside to dry.


Prep the hot peppers

Before handling peppers make sure that you are wearing gloves. You certainly don't want to be handling peppers and accidentally touch your face!

Take the peppers and give them a good rinse in cold water. Dry them in a towel. Then take the peppers and slice them in half. At this point you can remove the core and seeds. If you love the heat then leave the seeds in.


Charring the peppers

The main concern while charring the peppers is to char only the outside skin and not the flesh. Grill or broil the peppers and keep a close eye on them all the time. Keep turning the peppers at regular interval and it would be ready within 15 minutes.


Steam the peppers

Take the charred peppers in a paper bag and the steam them for 20 minutes. After removing them from the steam the skin would be easy to remove just by rubbing them with hands.

Note: People who love pepper skin should avoid charring and steaming the peppers. They can jump directly to the next step.


Add the spices

Now add the garlic cloves to the sanitized jar. You can also add some other herbs or aromatics like oregano to enhance the taste.


Peppers in jar

Now pop your hot peppers into the jars. Make sure that you leave 1 inch headspace at the top of jar. Then add the kosher salt as per your taste. Remember salt only enhances the taste, it is not a preservative.


Prep the preservative

In a pot, combine water, vinegar, salt and olive oil and then bring them to boil. Then let it simmer for a couple of minutes.


Add the preservative to the jars

Use the ladle or big spoon to transfer the preservative from the pot to the jar. Do not fill the jar completely. Leave an inch of headspace. Put the lid on the jar and seal it.

Hi I read quite a few articles that claim the peppers have to be canned in a pressure cooker? Is this true?I am using 4 oz mason jars.
Thank you
These require refrigeration after canning per instructions, they are not stored on a shelf. Therefore this method is preserving, but does require refrigeration.
