I would like to put some chillies in olive oil as I have so many, but do I have to heat the oil or cook the chillies? I want them to stay nice and red, and I want them to keep a long time so I can give them as presents.
I once made the mistake of popping whole chilies into the oil, but this is not the correct way. You have to gently fry the chopped chilies in the oil and then strain back into a bottle once cooled.
You can even add garlic and any herbs you fancy.
