Take a pot. Wash it properly and allow it to dry.
Now add flour, half teaspoon of salt, one teaspoon of mustard, one teaspoon of sugar, one fourth cup of vinegar, half teaspoon of white pepper and water in it.
Mix all of them thoroughly till a good consistency is achieved.
Now start cooking on a medium flame and keep on stirring simultaneously until the mixture becomes very thick.
Now remove the mixture from hob and add egg yolks in it, one at a time. Beat the mixture them with the help of beater.
Now slowly add oil in it and beat again. If you think that the mixture is becoming too light, it means that the amount of oil being used in not appropriate. What it also means is that you might have neglected a step in the previous processes. This however can always be covered up, by adding the oil slowly and checking up on the consistency.
Now take a jar. Wash it thoroughly so that there is no flavour of the previous product which was in it. Allow the jar to dry completely and then add the mayonnaise mixture in it.
Cool the mixture in the fridge before serving. Your egg mayonnaise is ready.
