In a mixing bowl, blend 4 egg yolks, 1 teaspoon salt, 2 tablespoons sugar, and 2 tablespoons vinegar using a mixer.
Very slowly add 1 cup of salad oil, drop by drop, mixing thoroughly after each addition.
Once the first cup of oil is well incorporated, add the remaining oil a little faster, but make sure to blend each addition before adding more.
When all the salad oil has been added, stir in 4 tablespoons of vinegar.
In a saucepan, combine the flour (or cornstarch), 1 cup boiling water, 1/4 cup vinegar, 1 tablespoon salt, and mix until it’s a smooth paste. Cook over medium heat until thickened.
Add the hot mixture to the mayonnaise base and blend well until smooth.
Pour the finished Miracle Whip Copycat into a container and cool in the refrigerator before use.
Notes
For a thicker consistency, use cornstarch instead of flour.You can adjust the sweetness by adding more or less sugar based on your preference.Experiment with different vinegars like apple cider for a unique flavor.
