There are two basic ways of making mayonnaise. One uses a food processor or blender. The second, quicker version uses an immersion blender. Watch our video how it's made. http://www.cookkosher.com/index.php?option=com_zoo&task=item&item_id=334&Itemid=8
1½ cup oil
½ garlic clove (optional)
2½ Tbsp lemon juice (juice of ½ lemon)
¼ tsp salt
1 pinch black pepper
Add oil to a tall jar. Add garlic, lemon juice, egg, salt and pepper.
Insert the immersion blender and blend, without moving the blender, for 2 minutes.
When the mixture begins to thicken, move the immersion blender up and down until mayonnaise is emulsified.
