How to Preserve


Bell or sweet peppers

Sweet or bell peppers can be frozen without being blanched; however, because they are limp when they are thawed, it is best to use them in cooked dishes. Select crisp, tender green or red pods.  Wash, cut out the stems, cut in half and remove the seeds.  The peppers can then be cut into rings or ½-inch strips or diced.

To blanch (which helps maintain crispness in frozen peppers):  Blanch peppers that have been cut in half in boiling water for 3 minutes. Strips and rings should be blanched for 2 minutes.  Cool promptly, drain, pat dry so there is no water sticking to the produce. Then package, seal, label and freeze.

Hot peppers

Hungarian, Hot Wax, chili (numerous varieties), Habanero (extremely hot)

Wash the hot peppers, cut them open, remove the seeds and stem them.  Package raw.  Seal, label and freeze.  Caution:  when handling hot peppers, wear rubber gloves to prevent your hands from burning.  Do not touch your eyes.


Select firm, crisp, deep red pimentos.  Peel by roasting in an oven  at 400 to 450 degrees F for 6 to 8 minutes or until the skins can be rubbed off.  Wash off the charred skins.  Cut out the stems and remove the seeds from the peppers.  Package, seal, label and freeze.


Food safety tip:  Peppers MUST be pressure canned for a specific period of time to avoid the potential of the food-borne illness botulism.

Hot or sweet peppers

Select firm yellow, red and green peppers, such as bell, chili, Jalapeño and pimento.  Do not use soft or diseased peppers.  Wash and drain the peppers.

To prepare chili and tough-skinned peppers: (CAUTION:  wear rubber gloves while handling the chilies or wash hands thoroughly with soap and water before touching your face!)  Wash and dry the chilies.  Slit each pepper on its side so steam can escape during roasting.  Place the peppers in the oven at 400 degrees F or under the broiler for 6 to 8 minutes until the skins blister. 

Allow the peppers to cool, then place them in a pan and cover them with a damp cloth to help make the peeling process easier.  After the peppers are cool enough to handle (several minutes), peel each pepper.  Remove the stem and seeds from the peppers.

To prepare pimento peppers:  Scald the peppers in boiling water for about 15 to 20 minutes or roast them in the oven at 400 degrees F for 6 to 8 minutes or until the skins are blistered.  Rub off the skins.  Remove the stems, blossom ends and seeds.  Flatten the pimentos.

To prepare other peppers:  Remove the stems and seeds.  Blanch for 3 minutes. 

Hot Pack

Small peppers may be left whole; large peppers should be quartered.  Pack peppers loosely in hot jars, leaving 1 inch headspace.  If desired, add ½ teaspoon of salt per pint.  Fill the jar to 1 inch from the top with boiling water.  Remove the air bubbles.  Wipe the rim of the jar.  Adjust the lid and process.
