Peanut Butter Fudge

Here's a recipe for ABSOLUTELY FOOLPROOF peanut butter fudge.
From: gt2067c@prism.gatech.EDU (J. Paul Patton)

2 cups sugar
1 cup peanut butter
¾ cup milk (I've always used 2??, but whole milk will probably work fine)

Stir milk and sugar together
Slowly bring to a soft boil (stirring occasionally)
Continue boiling for 10 minutes (stirring occasionally)
Stir in peanut butter until smooth and creamy (it needs to look like a
homogeneous solution)
Pour into a buttered or greased pan to cool (a 9x9 pan works best, I've found)
