I haven't read what everyone else said yet, but I did this nearly exactly the same this past summer and I have one word of advice . . . don't use extra virgin olive oil.
I only made it because I needed mayo and couldn't go to the store, but if I do this in the future I won't use olive oil, that's for sure.
Also, my mom and I were making it together (family gathering at my house) and using the stick blender and watching it thicken up made us both laugh really really hard. I guess you had to be there though.
