Peanut butter is good. Here's the recipe.
There is a butter churn at the farmyard.
Fix it
You have the new butter churn. Deal with it.
Add the milk and the peanuts into the cylinder... I mean butter churn.
Then, churn.
Did you get keys to the Maverick's time machine, already?
Start the time machine and the hood pops. Open the hood. As you can see the motor is missing one cylinder head.
Insert the cylinder head, with milk and peanuts, into the motor.
Peanuts, it was nice to know you.
