If you're making a video of a recipe, it seems to me like a unique opportunity to focus in more detail on what it looks like when each step is done properly.

The one that always comes to mind is when I'm baking and the instructions say to whip egg whites until soft peaks form. When exactly is it "soft"?! Sure, I know now, but I definitely didn't know back then, and as it turns out a video is a great way to get the point across.
