Since the resulting discussion was almost entirely about making mayonnaise, we moved this thread over to our Home Cooking board: http://chowhound.chow.com/topics/872981
However, FinnFPM was looking for a place to buy olive oil mayo in his/her original question:
Has anyone seen this for sale around the city anywhere? North End perhaps?
I saw an advertisement for Spectrum brand's product, but then went to the store and realized that it was just canola/soy mayo with some olive oil mixed in. Angry, I wondered if the above product exists here at all.
So, if you've got more tips on fixing his home-made mayo, please jump to the Home Cooking thread, and if you've got local tips on where to get it, please post here in this new thread.
