The Benefits of Squeezing Lemon Juice on Fried Eggs
The Science Behind It:
Eggs are a great source of protein, and lemons contain citric acid. The acid in lemons can react with the proteins in eggs, forming an airier structure and resulting in a softer texture.
Food scientist Makenzie Bryson Jackson provides two explanations for why adding lemon juice to eggs makes them fluffier when fried.
Firstly, the proteins in eggs (40% in the yolk and 60% in the white) coagulate and form a 3D structure when heated. By adding a small amount of acid, such as lemon juice, the proteins form a firmer structure that traps air bubbles. This results in the perfect fluffy texture for fried eggs.
Secondly, the liquid (lemon juice) slows down the coagulation of the eggs. Similar to adding water or milk, the lemon juice dilutes the egg proteins. This prevents the proteins from setting too quickly, and the cooking process is slower as it takes longer for the liquid to evaporate. The steam created by the evaporation contributes to the softer, fluffier texture of the fried eggs.
A Word of Caution: While lemon juice can enhance the texture of fried eggs, it’s important to use the right amount. Too much lemon juice can affect the taste and cause the eggs to curdle or become too watery due to the excess acid and liquid, respectively.
According to Makenzie Bryson Jackson, the ideal ratio is ½ teaspoon of lemon juice for every 6 eggs used.
Alternative Ingredients: If you don’t have lemons on hand, you can achieve similar results with vinegar. Additionally, adding water, milk, or a small amount of melted butter can also make your fried eggs tastier and fluffier.
Bonus Tips for Cooking with Lemons:
– Reduce Saltiness: If you’ve oversalted a dish, add a splash of lemon juice or other acidic ingredients like vinegar or tamarind to balance the flavors. These ingredients will help reduce the saltiness and create a more harmonious taste. Always add acidic ingredients gradually and taste as you go to ensure the flavors are to your liking.
– Prevent Oil Splatter: Before adding food to hot oil for frying, drop a few slices of lemon into the oil. Use chopsticks or tongs to hold the lemon slices and rub them around the pan. Alternatively, squeeze a few drops of lemon juice into the oil before adding the food to be fried.
– Eliminate Fishy Odors: When preparing fish or other strong-smelling proteins like duck, use lemon juice to neutralize the odor. The acid in lemons is great for cleaning and removing any unwanted smells from your hands and the food itself.
