As others have said, you're not going to get a lot of purchases without being able to preview what it does first (maybe build some slightly contrived examples?).

I wish there were just a standardised way for recipes to be presented. If I'm on a desktop or tablet, I want ingredients on the left, method on the right, a picture of how it's supposed to look at the top, perhaps some serving suggestions at the bottom, and maybe a few interstitial pictures/videos in the method if it's something really difficult (I'm happy for these to appear in a modal). On mobile, I want the ingredients at the top and the method beneath it. I never want the life story. Having comments at the bottom is sometimes quite nice but fairly optional. I'd like to be able to toggle units to things that I'm comfortable with (I don't want ounces and cups but it should be possible for people who do).

This shouldn't be too much to ask, it really shouldn't.
