The recipe:
Ingedients:
100 ml milk 200 ml oil Lemon juice Salt
Instructions:
- Whiz 100 ml milk up - 30 secs
- Slowly add 200 ml oil
- Move the blender up and down to help emulsify
- Flavour with salt and lemon juice
- Whiz up until thick
"Note: It's NOT 100% fool proof – if blender is hot the mayo splits."

This is not the first time I see this kind of recipe, how do oil and milk emulsify? Why the note says that when the mixture gets hot it starts to separate and what's the purpose of the first step "whiz the milk up before adding the oil"?
