White Vinegar (Best Option)
1/2 teaspoon per 2 eggsWhite vinegar contains acetic acid, which provides the necessary acidity to brighten the eggs and help denature proteins for a tender texture. The acidity also balances the richness of the eggs, enhancing overall flavor.
Use sparingly to avoid an overly vinegary taste. Mix it well with the eggs before cooking to ensure even distribution. Start with the recommended ratio and adjust slightly if needed.
Compared to lemon juice, white vinegar is less aromatic but equally effective in improving texture and flavor brightness, making it the closest functional substitute.
