This is fantastic!
The systems are great and build on each other really well, great work there!
The only suggestions I'd have are for quality-of-life improvements, like 'bookmarks' in the book to go from section to section, and clear indicators of what's a clickable link in the book vs just a title. Another suggestion would be actually seeing the ingredients and dragging them onto the plate, rather than words onto a menu.
But! Those are just nice-to-haves. Overall, this is completely working and really fun! Also, the art is really cute!
Great work!
