This homemade mayonnaise is created very easily in about 10-seconds using a stick (immersion) blender.
After chilling in the fridge, this mayonnaise gets
slightly thicker and tastes very much like Best Foods/
Break egg into bottom of 1-quart canning jar or other tall narrow jar. The jar should be only slightly wider than the end of the stick blender.
Add lemon juice, vinegar, mustard, table salt and white pepper.
Add 1 cup of vegetable oil.
Place mixing blades of stick blender (turned off) all the way to the bottom of the jar, pressing down over the egg.
Turn stick blender on high speed, hold in place at bottom of jar for about 5-seconds, until you see mayonnaise form under stick blender's mixing blades.
Slowly pull stick blender upward until the mixing blades reaches top of jar, taking about 5-seconds to do so. The stick blender will turn the oil into mayonnaise as it is pulled slowly to the top of the jar.
Chill before using to allow mayonnaise to thicken slightly and for flavors to develop.
