I think the answer is:
Life
To make this recipe, you'll need a really good kitchen
Earth is a unique planet with the conditions "just right" for life
Our neighbors, for example, couldn't even use it to make a chicken
Any other planet in our solar system failed to create complex life forms
Above all, your temperature setting has to be good
Earth is fairly mild relative to all the other planets out there
Otherwise it won't work, and you won't get any food
No complex life forms found on other planets (yet)
When you've set up the ingredients, add water and wait
Earth had the right chemistry, conditions and water (possibly from comets) to produce simple life
It may take a while, don't be alarmed if it gets late
It took millions of years for life to rise on earth, even with proper conditions
When it's done it'll be worth it, I promise you that
The fact that so many species exist on this planet is a beautiful thing
You'll have so much to eat, I'm sure you'll get fat
Lots of living things to eat
The one time we tried it, it was quite a success
So far we know abiogenesis has only happened on our planet. As a result of that, millions of species (and counting) exist today: quite successful given that there were possibly very few to begin with.
Though I dare say it made a bit of a mess
The interactions between living organisms are messy. The mess could also refer to our actions - polluting the planet.
