Crush the garlic in a food blender. Add the egg, and blend for 15 seconds. Very slowly add the oil through the top of the blender so that an emulsion can take place. Stir in the lemon juice by hand. Hint: To get the smell of garlic off your hands, simply rub your hands in used coffee grinds. End of odor. In Italy, it is common to eat a whole coffee bean after a big meal so that your lover will not be bothered by garlic.
