Add only 2 tablespoons of oil to food processor. Reserve the rest for later.
Add the rest of the ingredients into the food processor.
Turn the food processor 'on' Once all of the ingredients have mixed, begin slowly drizzling oil into the food processor.
If using a whisk:
Add only 2 tablespoons of oil to your bowl. Reserve the rest for later.
Add the rest of the ingredients into the bowl.
Whisk all of the ingredients together well, and then while actively and violently whisking begin very, very slowly drizzling oil into the bowl. This should take you a couple of minutes.
Notes
Here is the stick blender I use and here is the food processor I use. Both work wonderfully to make homemade dressings!
