I just made the mayo Mama and it turned out excellent using your recipe. I did add a bit of sugar though.
I have seen several for the Miracle Whip but haven't attempted it yet. I like Miracle Whip for salads too. I might make a batch today and will let you know how it turns out later.
Thank you.

You're welcomed and I am curious!

Mama, I just made up a batch of the Miracle whip. I used the whisk on the stand mixer this time instead of pulling out the blender again. I went with vinegar because to me that is the taste behind Miracle Whip. Gives it that tang I like. I taste tested after whisking in the last 1/2 cup of oil and adding 2 more tablespoons of vinegar and it tasted spot on to the real thing. I then added the hot mixture of Vinegar, dry mustard and cornstarch and mixed. I taste tested again and to me it was a bit over the edge on tartness but a perfect creamy consistency. I guess that a total of 5 tablespoons of vinegar for this recipe was just a bit to much. Next time I will go with 2 tablespoons of lemon juice and 1 tablespoon of vinegar with the egg yolks and oil mixture and keep the 2 tablespoons of vinegar in the hot mixture.
Also, when I added the cornstarch, dry mustard and vinegar to the cup of boiling water it thickened up right then and there. Odd that the same amount of corn starch to flour is used, Usually 1 tablespoon of corn starch equals 2 tablespoons of flour for a thickening agent. But, as I said, the consistency was perfect after everything was mixed together.
I hope I gave you a good description of how it turned out. This recipe is a keeper with minor tweaking.

I had a couple taste testers come to my aid mama and with the addition of another tablespoon of powdered sugar I have the flavor everyone is looking for. The additional sugar balanced out the tartness really well.

I have been making homemade mayo every since way back when this post first got started we love it, and I sold my neighbors on making it also! A huge savings, and I use only cannola oil, much healthier alternative!
