Mayonnaise

This recipe is courtesy, my friend's mom! An extremely sweet assamese lady who was also a wonderful cook. Once I recieved a jar of home-made mayonnaise from her and instantly fell in love with the stuff. This is her recipe. Hope you enjoy it as much as I did :-)
For people, who don't like the idea of high cholestrol egg yolks, use milk powder or soy milk instead. Don't forget to tell me how it was :-)

Egg yolks 2
Salt & pepper
Dry mustard powder 2 tsp
Castor sugar 1 ½ - 2 Tbs
White vinegar or limejuice 1 Tbs
Garlic paste[opt] 2 tsp
Olive or sunflower oil 300 ml
Boiling water 1 ½ Tbs
Except for the oil, put all the other ingredients into a blender and blend for a couple of minutes.
Add the oil a drop at a time, and then in a steady stream until the mayonnaise thickens. Add boiling water to prevent the mayonnaise from curdling. Store in a clean bottle in the fridge.

PS:All ingredients at room temperature.
This quantity makes 300 ml of mayonnaise.
