How to Cook

This came as a quick visual idea, and what i ended up with takes a while to place two digits in the grid. But after that it's pretty easy.
Normal Sudoku rules apply.
Alien: adjacent digits on a green line have a difference of at least 5.
Book: adjacent digits on an orange line have a difference of at least 4.
Drool: the light blue blob of saliva connects two consecutive digits.
Space helmet: blue lines are split up by region borders and total to the same value per region. Different lines may have different totals.
Book Cover: The ink blots connect digits in a 1:2 ratio.
The fancy spelling of "to" is due to the author being a Prince fan.
Humans are insignificant in the grand scheme of things. Also for some reason the title is printed on the back and front. Ignore that. It's an alien edition.
Space Dust: the book is partially covered in dust. You can blow it off by entering a few particular cells correctly.

Nice puzzle, not too difficult. Hopefully it's "for humans"
