My son wants to make them. I googled 1,000 year old eggs and it seems there are a lot of different ways to make them, all of which seem pretty involved. He has Asperger's so nothing is ever simple with him. He wants to order quicklime and rice chaff from Amazon (haven't checked to see if they carry it yet) and whatever else we need and let them ripen in the backyard all summer. I am willing to let him try but I want to know just how bad they smell because we have neighbors. Has anyone made them or know someone who has? I told him that I want to try and find one at an Asian market before we buy all the crap for it. Any advice?
