This pie is simple to make. I recommend using a heavy pan for mixing, and a good, professional quality whisk-it makes the job much easier.
For the Crust:
1 1/2 cups finely crushed graham crackers
1/4 cup sugar
1/4 cup soft butter
Mix well and press into 9 inch pie plate. Bake in pre-heated 375 degree F. oven for 8-10 minutes. Cool before filling.
For the Pie:
2/3 cup sugar
1/4 cup cornstarch
1/2 teaspoon salt
2 cups milk
1 cup maple syrup
3 egg yolks, beaten(keep in a large bowl)
1 tablespoon butter
1/2 teaspoon vanilla extract
Combine sugar, cornstarch, and salt in a large, heavy pot. Gradually add the milk and syrup. Whisking briskly and constantly, keep mixture moving until it thickens and boils. Gradually add the mixture to the eggs. Replace it in the original pot and return to heat cooking over low heat and whisking until the mixture becomes very thick. Stir in the butter and extract. Cool slightly before pouring into prepared crust. Chill. When cool, top with whipped cream.
