What makes Dutch baby rise?

[Emsom]

Hello everyone, ever wonder what makes a Dutch baby pancake rise so impressively? It’s all about the batter's high egg and liquid ratio, creating steam when heated, which causes this treat to puff up dramatically in the oven. No leavening agent is needed, just a hot pan and the right heat. What are your thoughts on this?

From what I gather, the batter's composition helps create steam, which pushes the Dutch baby up as it bakes. That's my understanding, at least!
