to something it’s a good idea to let it sit for a bit so that your end result will be much fluffier.
My recipe makes 2 cups of batter. Another good reason I use the Pyrex is because I can see how much batter I used for each pancake and make them all the same size if I want. My recipe makes 4 good sized pancakes so I pour ½ Cup per pancake and they all end up the same size.
What it looks like just after pouring, it will still spread out a bit.
