I have never made one of these at home before, but I am a huge fan of them at restaurants. I make crepes often and tried the little pancake/popovers once (disaster, they all stuck) but never a Dutch Baby until this week and it was so exciting and delicious and easy, I am worried.
Here's what I did: (There are so many recipes out there, I don't know where I jotted this one down from.)
Pre-heat your oven to 425 degrees and put in 2 TBL butter in a cast iron pan, mine was about 10". Stick the pan into the oven to get the butter melty and the pan hot. While that is heating up mix 4 eggs, 1/2 cup flour and 1/2 cup milk. Pour this mixture into the pan on top of the melted butter set the timer for 20 minutes. Mine here was at 25 minutes because I like them crispy.
We had ours with lemon juice, maple syrup, and powdered sugar.
