The seccond attempt worked great. However, I used a stick blender and while it worked, it was a bit difficult because it gets so thick.

Next time I will use my cuisineart food processor as stated in the instructions. (I did not use it this time because I had just used it for something else and did not want to take the time to wash it out. Big mistake! It would have been faster than having to make it twice.)

Note: I did not put in the pepper because I have never seen mayo with specks. It was great without!
