I am always rubbing my eyes and have often, after cutting a chilli, received a nasty hot sting that has blinded me for a few minutes. To avoid transferring the heat to your eyes or skin, there are a couple of things you can do – wear plastic gloves when cutting; or rub the fingers of one hand with some olive oil (the hand you are holding the chilli with, not the hand you are holding the knife). Only touch the chilli with the oiled hand and then wash with hot soapy water.
