3/4 cup graham wafer crumbs
3/4 cup ground almonds
1 tablespoon granulated sugar
1/4 cup butter, melted

Preheat oven to 350 degrees F.

Increase oven temperature to 450 degrees F.

In a large bowl, using an electric mixer, beat cream cheese and sugar until very smooth. Beat in eggs, one at a time, until just blended. Beat in remaining ingredients. Pour into pan. Bake for 10 minutes, then reduce heat to 250 degrees F and continue baking for 35 to 45 minutes or until center is just set. Remove from oven and run a knife around the rim of pan to prevent cracking. Cool thoroughly at room temperature.
