Do you love red, yellow or green? Pick your favorite color at any growth stage of your chilli pepper plant. However red and yellow peppers tend to be more fragrant. Peppers are ripe when their color is vibrant and peppers look nice and plump.
If you have a good harvest, you can string your peppers and let them dry in a well ventilated shaded spot. I use dried chilli peppers on Pizza and salads and sometimes even add them to my Spagetti sauce for an extra punch of spicy.
