Preserving chili by drying
Drying is one of the simplest and most effective ways to preserve fresh chili peppers, saving time and effort. When dried, chili peppers will lose their spiciness but still retain their characteristic aroma, which can extend their shelf life. The steps for drying chili peppers are as follows:
- Rinse the chili and dry it with a towel.
- Cut off the stems of the chili peppers, remove any damaged ones, and split the chili peppers in half lengthwise to increase the surface area exposed to heat and wind, shortening the drying time.
- Arrange the chillies evenly on the tray, spreading them into a thin layer. Line the tray with foil so that the essential oil in the chillies is not lost much during the drying process.
- Dry the tray of chili peppers in the sun for 2-3 days until the chili peppers are crispy and dry. If you need to dry them faster, you can use an oven or microwave set to 50-60 degrees Celsius for about 1-2 hours.

- With dried chili, you can completely rest assured to store and use it for more than 1 year without changing the quality, without worrying about mold or damage.
Dried chili peppers are easily ground into powder, convenient to use in food processing, suitable for many different recipes from stir-frying, cooking, stewing, braising...
Use salt
Salt is known to have antibacterial and moisture-absorbing properties, so it plays an important role in limiting the growth of bacteria and mold that cause chili to rot. If you want to reduce the spiciness of chili and prolong the storage time of chili, you can apply this method:
- Wash the chili, drain and dry thoroughly.
- Cut the chili into round slices, each slice about 2-3cm thick.
- Prepare a clean tray, spread the chili peppers evenly on the tray, sprinkle salt on top. The amount of salt sprinkled must be enough to cover the entire layer of chili peppers.
- Leave the chili tray alone for 1-2 days to let the chili release all its water and absorb the salt.
- After the chili has absorbed the salt, scoop it out and put it in a plastic box with a tight lid or soak it in cooking oil to extend its shelf life.
This way of preserving fresh chili for a long time will help the chili not be too spicy, a bit salty but still have an attractive aroma. You can use salted chili to eat raw, mix in salad or as a cooking ingredient.
