Chocolate Cream Pie

I have another chocolate cream pie recipe that uses only chocolate (no cocoa powder, like this one). That one and this one are both very good (and very chocolatey!). I've never made them both at the same time to do a side-by-side comparison of which one's the best. If you don't have heavy cream on hand, the other just uses milk...

Ingredients
2/3 c sugar
3 T cornstarch
2 T cocoa powder (I use dark)
dash salt
1 C heavy cream
2 C milk
3 egg yolks
1½ C semisweet choc
2 T butter
1 tsp vanilla

One 9" pie crust
          A standard pie crust is fine.
          A graham cracker or chocolate cookie crust is good.
          A chocolate shortbread crust is my personal favorite!

Directions
Combine sugar, cornstarch, cocoa powder and salt in a saucepan. Slowly whisk in, a little at a time, cream milk and egg yolks. Heat gently to a boil; boil 1 minute. Remove from heat.

Blend in semi-sweet chocolate, butter and vanilla, stirring until chocolate and butter are completely melted. Pour into prepared crust.

Once cooled, cream pie may be spread with a generous layer of whipped cream before serving; garnish with chocolate curls...
