Mayonnaise is simple to make and is much tastier than the commercial varieties. It contains raw eggs so should be stored in the refrigerator until ready to serve and it is best to use free range or organic eggs. Home made Mayonnaise is best not served to the old or very young, in this case use a good commercial Mayonnaise, sour cream or crème fraîche, simply adding the finely chopped herbs and a little lemon juice if using sour cream or crème fraîche.
