Why does the second batch of pancakes brown much faster?
The second batch of pancakes may brown faster due to residual heat in the pan. The first batch of pancakes can cause the pan to heat up, and if the pan is not cooled or cleaned properly, the residual heat can cause the second batch of pancakes to cook faster and brown more quickly. Additionally, any grease or batter that has accumulated in the pan from the first batch can also contribute to faster browning. To avoid this, it's best to let the pan cool to room temperature between batches, or wipe it down with a paper towel to remove any residue before cooking the next batch.
But there's no harm in just letting the second batch brown faster, right?
There is no harm but you will need to keep in mind the reduction of the cooking time to achieve the same colour. Also the thickness of the pancakes as they might not cook through without burning the outside. A medium heat is your best bet to achieving consistently delicious and aesthetically pleasing pancakes.
