Don’t overmix. I know. I said it already. But I’m saying it again. Overmixed bread flour batter makes dense, rubbery pancakes. Lumps are your friends, remember?
Don’t skip the rest time. If you’re in a rush, these aren’t your pancakes. Give the batter those 15 minutes. It’s like a spa day for the gluten.
And don’t press down on the pancakes with your spatula while they cook. That’s pancake abuse. Let them be puffy.
