No, this isn't a dream. This is clean eating mayonnaise at it's finest. Yum!
Place all ingredients in a tall jar or cup that fits your immersion blender.
Using your immersion blender, blend for less than 30 seconds until you have mayonnaise.
Store in refrigerator immediately and up to 1 week.
Storage Notes: There are varying opinions on the shelf-life of homemade mayonnaise. Some people won't keep their mayo longer than three days no matter what, while others say it expires when the date on the egg carton says so. I have found that a week is just about right. You'll notice a slight change in flavor, consistency and sometimes even color when it starts to turn. But above all, please keep it in the fridge at all times! There are also plenty of folks out there that do not use pasteurized eggs. That is your prerogative. With a little one at home, I tend to err on the side of caution and use the pasteurized eggs for this.
