Don't be afraid of homemade mayo!
Taking a big mesuring cup put in it:
1. Two whole eggs
2. a big pinch of salt
3. Two Tb spoon of dijon mustard
Using a stick blender. Blend the whole thing. Then while blending, pour olive oil in it.
For a thick mayo, you need about about 2 cups of olive oil.
ratio: 1 egg-1cup olive oil
If its not thick enough add some oil and blend well.
