The fluffy pancakes are dependent on the balance of moisture, protein content, and heat control. There are a lot of home cookers who are concerned about baking powder or mixing time, but they do not pay attention to the liquid base. Normal milk works but something in the pantry is usually better. The concentration of proteins and concentration of water in evaporated milk are higher and less respectively. These variables affect the thickness of batter, air retention and browning. Even minor liquid choice variation results in a stable texture without introducing additional measures.
Learning about Pancake Structure

Pancakes depend on the development of gluten and gas expansion. Flour helps in structure, eggs hold together and baking powder releases carbon dioxide. Liquid moisturizes flour and restrains the batter flow. Hydration makes the bubbles even as they are formed during cooking. When the batter is made too thin gas will escape and the pancake will be flat.
Why Regular Milk Falls Short

Ordinary milk has approximately 87 percent water. Structural weakness is caused by high content of water, which makes batter thin. Humidity inhibits the process of browning as moisture has to evaporate before caramelisation takes place. The outcome is a paleness on the face and an uneven lift. The texture is soft without being heightened.
The Difference between Evaporated Milk and regular milk

According to evaporated milk, the amount of water is almost two times less than that of fresh milk. The liquid is heated until it becomes liquid and this process takes away the moisture that concentrates proteins and lactose. Increased protein concentration promotes structure in the presence of heat. Lactose enhances better browning by the Maillard reaction. These modifications enhance the texture and surface color.
The influence of protein on the fluffiness

Milk and egg proteins are network forming proteins. The presence of a better network captures gas emitted by baking powder. Evaporated milk is more proteinated per cup when compared to standard milk. This reinforcement retains longer air pockets. After the pancakes are flipped, they puff up and hold their shape.
Effects on the consistency of Batter

Batter of greater thickness holds bubbles formed in the process of mixing. Evaporated milk makes a thicker mixture without the addition of more flour. This balance eliminates the chances of getting overmixing which may harden the gluten strands. A runny batter is poured slowly on the pan, and it is rounded off. Height does not vary between batches.
Better Baking and Flavoring

The lactose of evaporated milk promotes caramelization during middle heat. Pancakes are cooked with a golden color and slight sweetness. Less water has to evaporate making browning quicker. The taste is more full without the use of sugar. This modification not only improves the appearance and taste, but it does not require additional ingredients.
Practical Substitution Method

Substitute the normal milk with an equal quantity of evaporated milk. In case the batter is too thick, then add about one to two tablespoons of water. Continue stirring until dry streaks are eliminated. Allow the batter to rest (five minutes) and then cook it. This rest period enables an equal absorption of liquid by flour.
Temperature Control in Cooking

Heat medium 175 to 190c on a flat griddle. The overheating of heat makes the food immediately brown but the middle remains uncooked. The medium temperature contributes to the stable growth of gas and equal baking. Turn twice when bubbles appear and sides are established. It takes approximately two minutes each side.
Storage and Convenience Advantages

Evaporated milk can be kept in the shelf in months before being opened. This capability helps in planning of meals without spoilage of dairy. When refrigerated, quality is maintained within four days after opening. One of the staples in a pantry minimizes last minute shopping. The replacement also takes place in waffles and quick bread.
Common Mistakes to Avoid

Do not overmix after adding evaporated milk. Excessive agitation fortifies gluten and softness is diminished. Do not over dilute the batter with water. Keep the temperature of the pan moderate to avoid uneven rise. The standard size of the portions assures the same time and thickness of cooking.
