Immersion blender for salad dressing
I want to make a lemon poppyseed dresssing using my immersion blender. I know that when using a blender or whisking by hand, you add the oil slowly to incorporate it. When I use the immersion blender can I just add all the ingredients, including the oil, at once, and then blend away? Do I have to add the oil separately and slowly?
Yes it is the best method but if you are using something as an emulsifier then it really doesn't matter too much. I make most of my dressing in little jars like what capers come in. A little dollop of mustard will keep the oil and vinegar mixed for a long time. Other common emulsifiers that work well would be egg yolk and mayo.
I add all the ingredients into a glass that just accommodates the blender's diameter, leaving room at the top for displacement and possible volume increase. I immerse the blender to the bottom of the glass, turn it on and s-l-o-w-l-y draw the blade upward, incorporating the ingredients. I also aioli this way and have never had any problems.
I like immersion blenders for dressing. Even if you add all the ingredients at once you end up with a creamy dressing.
