⭐ Lemon Juice (Best Vegan Option)
1 teaspoon per 1 tablespoon of white vinegarLemon juice works well as a substitute because it contains citric acid, which mimics the sharp acidity of white vinegar. This acidity helps to slightly tenderize the eggs and balance the richness of cheese or vegetables in the frittata.
When using lemon juice, ensure it is fresh for the best flavor and avoid adding too much to prevent an overly tart taste. Start with the recommended ratio and adjust slightly if needed based on your taste preference.
Compared to white vinegar, lemon juice imparts a slightly fruitier note but maintains the overall balance of the dish, preserving the frittata’s light and fluffy texture.
