Lemon Juice (Best Option)
1 teaspoon per 2 eggsLemon juice contains citric acid, which mimics the acidity of white vinegar, helping to break down proteins in the eggs slightly and improve tenderness and fluffiness. The acidity also enhances the overall flavor profile by balancing richness.
To use lemon juice effectively, add it just before cooking to avoid curdling. Freshly squeezed lemon juice is preferred for the best flavor and acidity.
Compared to white vinegar, lemon juice imparts a slightly fruitier note but maintains the desired acidity, resulting in a similarly tender and flavorful omelette.
