You might want to wear gloves to protect your hands as you handle the chilies. Hot chili peppers contain capsaicin, a chemical that burns when it gets on your skin. Take special care not to touch your eyes or nose after handles hot chilies.
Put the tray in a sunny, well-ventilated room. The kitchen windowsill is a great spot. Let them dry for three or more days, then store them in an airtight container.
Thread a needle with a long piece of strong thread or fishing line. Pierce the chilies just under their caps to thread the needle through them. Do this until all of the chilies have been threaded. Hang them in a well ventilated and sunny place in your home. In three days to a week, they’ll be dry and ready to use.
Slice the cleaned chilies in half lengthwise. Lay them seed-side up on a baking sheet. Bake at 125 °F (51. 7 °C) (or your lowest setting) for several hours. This is still a lengthy process but quicker than air drying. You could also use a food dehydrator for quick results. [2] X Research source
If you want to flavor the chilies, mix in three tablespoons of salt and 15 peppercorns before packing the chilies. This will lend the chilies a flavor similar to that of pickled jalapeño served in restaurants. Other spices, such as bay leaves or fresh herbs, can also be added to the mixture to flavor the peppers.
If you want the peppers to have a sweet flavor, dissolve six teaspoons of sugar into the vinegar. Let the contents of the jar cool for a few minutes.
Pack the bag as tightly as possible, so there’s little extra air in the bag. Air will make the peppers spoil faster. Freeze for several months. When you want to use the peppers, simply leave them out to thaw or blanch them in boiling water for a few seconds.
Lay the pieces on a baking sheet and freeze them for an hour. This is called flash freezing. Put the pieces in a storage bag and remove the extra air. Store in the freezer for up to several months.
Preheat your oven’s broil, or prepare your grill. Roast the slices until they’re charred. Under the broiler, this should take just a few minutes. Turn them once during the process so they cook evenly on all sides.
