For the uninitiated, a Dutch baby is a large baked pancake akin to a popover. Read more about them here, then check out the tips below to guarantee success.
• Make sure the milk, eggs and butter are at room temperature.
• It's important to preheat a heavy skillet so it's ready to go as soon as the batter hits the pan. A cold pan, especially something made of cast iron, takes too long to heat up while you're trying to cook the pancake.
• A 10-inch cast iron skillet is my go-to pan for these puffed-up pancakes, but you can also use a pie pan or other ovenproof skillet.
• As time permits, I like to give the oven a good half-hour to heat up and in the meantime allow the batter to rest. While everything warms up, I make coffee and enjoy a cup.
• Many Dutch baby pancake recipes call for using a blender to mix the ingredients. I haven't found this to be necessary, so I keep it low-tech: Just use a big wooden spoon and a large bowl.
• Double the amounts of flour and milk and add an egg for a heartier pancake that will serve three.
• Make it ahead of time for the puffiest, tallest pancake of all: Place batter in an airtight container and refrigerate overnight (or for up to three days), removing from the fridge while the oven preheats for baking. (Thanks to J. Kenji López-Alt, author of The Food Lab, for this tip.)
• The maximum puff of the pancake is ephemeral, and it begins to deflate seconds after it's out of the oven. Be sure to call over anyone you're brunching with to the oven so they can get the full effect of its grandeur.
