Anyone who dislikes making mayonnaise. This method is literally,

[SWv2]

Nope. I use one egg yolk, some mustard, salt, pepper, lemon juice, 200 ml vegetable oil, 50 ml olive oil. Bosh. Done in 30 seconds. The ingredients aren't important, just the method. Be sure that the stick goies right to the bottom and covers the egg yolk for the first ten seconds. And you need the tall, narrow jug to create the vortex. But it's so simple, so quick, and it never fails.

I thought olive oil was a very strict no-no.

Note I have never made mayonaisse.
