Radish's Homemade Butterscotch Pudding for Election Day Celebratory Dipping

2/3 cup brown sugar, packed
2 tablespoons corn starch
1/8 teaspoon salt
2 cups milk
2 egg yolks, slightly beaten
2 tablespoons butter*, softened
1 teaspoon vanilla

Mix sugar, cornstarch, and salt in 2-quart saucepan. Stir in milk gradually. Cook over medium heat, stirring constantly, until mixture thickens and boils. Boil and stir 1 minute. Stir at least half of the hot mixture gradually into egg yolks (this is the tricky part--stir constantly, to keep bits of cooked egg from forming). Blend into hot mixture in saucepan. Boil and stir 1 minute. Remove from heat; stir in butter and vanilla. Pour into dish. ALLOW TO COOL SLIGHTLY before dipping anything your spouse may want to use later, IYKWIMAITYD. Refrigerate leftovers.

* You can use margarine, but it will taste like crap.
