The main ingredient in a pancake is flour. Traditional pancake recipes feature all-purpose flour as the primary component, which provides the structure and texture needed for the pancake. Other key ingredients typically include milk, eggs, sugar, baking powder, and salt, which work together to create a fluffy and delicious batter. Pancakes can be customized with various mix-ins, such as fruits or chocolate chips, and are often served with syrup, butter, or fruit toppings. This versatile breakfast dish is enjoyed in many cultures, often varying in thickness, flavor, and preparation methods across different cuisines.
