On the other hand, having to constantly consult a recipe on my phone while I cook is the main quality of life aspect of home cooking that could be improved.

You're missing the part where I'm reminded that my phone autolocks so I have to go into the settings in the middle of cooking to make it never autolock (or be lazy and unlock it every time I need it). And then I have to find a clean knuckle to scroll the ingredient list and the recipe steps every time I'm trying to remember what step I'm at.

You could do some killer recipe UX with a HUD on some glasses.
