Is it ok to use waxed/conventional or bottled lemons vs organic?
It is ok but not recommended. If you only have access or a budget for conventional lemons though, simply peel it – this gets rid of the bulk of wax and any other preservatives or pesticides that may be coating the lemon. Be sure to wash the lemon with hot water and scrub off any dirt etc if you are not peeling it (organic doesn’t always mean clean or safe either).
