In a mixing bowl, whisk together the egg and sugar until smooth.
Ensure the egg and sugar are well combined to create a smooth base for the sauce.
Add the flour and mustard powder to the mixture, stirring until fully incorporated.
Sift the flour beforehand to avoid lumps in the sauce.
Gradually add the water and vinegar, mixing continuously to combine.
Adding the liquids slowly helps maintain a smooth consistency.
Transfer the mixture to a saucepan and cook over medium heat, stirring constantly, until the sauce thickens.
Keep stirring to prevent the sauce from sticking to the pan or forming lumps.
