I made a basic mayo a few days ago and was really happy with the taste but the consistency was a little thinner then I was looking for, I mixed by hand. I don't have the recipe in front of me but I think it was:
2 egg yokes
1 tbls grainy mustard (no dijon in the house)
3/4 cp veg oil
salt & pepper
I whisked together the egg, mustard, and lemon juice; then mixed in the oil a table spoon at a time to slowly incorporate, till i used 4 tbls then added a little more of the oil and whisked. I don't know if maybe i was whisking to fast or to slow and I did make it a point to not mix all the oil at once, I tried to whisk in a little at a time.
Any tips and tricks on mayo would be cool.
