I tried this recipe at least 5 times and it tastes pretty good. I substituted the sugar for Stevia (liquid form) and added a couple drops. You could also use Splenda or any other sweetener, just don't use too much. Taste as you add it in. You can make it in a blender, but I found it really easy to make it in a food processor.
Hellman's Clone
Yield: 1 cup
1 egg yolk (room temp)
2-1/4 teaspoons white vinegar
1 teaspoon water
1/4 teaspoon plus 1/8 teaspoon salt
1/4 teaspoon plus 1/8 teaspoon granulated sugar
1/4 teaspoon bottled lemon juice
1 cup canola oil
Whisk the egg yolk by hand for 15 seconds.
Combine vinegar, water, salt, sugar, and lemon juice in a small bowl or glass measuring cup. Stir until salt and sugar are dissolved. Add half of this solution to the egg yolk and whisk for another 15 seconds.
Pour 1 cup of canola oil (or soybean oil) into a plastic squirt bottle. This bottle will allow you to dribble the oil into the egg yolk with one hand while whisking with the other. Squirt a few drops of oil into the yolk and whisk, and continue to add oil a little bit at a time while whisking non-stop.
When you have used about half of the oil, your mayonnaise should be very thick. Add the remaining vinegar solution. Whisk. Now you can add the remaining oil in a steady stream while whisking until all of the oil has been added. Your mayonnaise should be thick and off-white in color.
Put the mayonnaise into an old mayonnaise jar and seal it with a lid. Leave this out on your kitchen counter for 8 to 10 hours so that the vinegar and lemon juice can kill any potential bacteria in the egg yolk.
Keep up to 2 weeks in your refrigerator.
