Put all ingredients into emulsion blender container.
Start with emulsion blender touching the bottom of the container. Blend for about 30 seconds until mixture begins to emulsify.
Once mixture has begun to emulsify, you can move the blender up and down until all ingredients are thoroughly blended.
Pour into glass jar and refrigerate to let the flavors meld. If you used the homemade ketchup recipe, the dressing will last for several months. Otherwise, it will last for 2-3 weeks.
