Amaretto Cheesecake

We have friends who love Amaretto, especially the husband. Because they are coming over tomorrow, I baked an Amaretto Cheesecake. Time to start making new recipes. Want to finish my cookbook. Guess that I was inspired by Julia Child's biography. She was certainly a force to be dealt with.
Here is the recipe:

Amaretto Cheesecake

Ingredients:
1 cup graham cracker crumbs
3 tablespoons white sugar
3 tablespoons butter
2 (8 ounce) packages cream cheese
1 1/4 cups white sugar
3 tablespoons cornstarch
1 (16 ounce) container sour cream
1 1/2 teaspoons vanilla extract
5 tablespoons amaretto liqueur
1/2 teaspoon salt
4 eggs

Directions:
1. Preheat oven to 350 degrees F (175 degrees C)
2. Mix together the graham cracker crumbs and the 3 tablespoons white sugar. Add the melted butter and mix well. Press into the bottom of a 9 inch springform pan. Bake in preheated oven for 10 minutes. Set aside.
3. In a large bowl, combine cream cheese, sugar and cornstarch, and mix until smooth. Add sour cream, vanilla, amaretto liqueur and salt. Mix until well blended. On low speed of an electric mixer, add eggs one at a time, mixing well after each addition. Pour batter over crust.
4. Bake in preheated oven for 60 minutes. Remove from oven. Loosen around the edges with a knife and cool on a wire rack while still in pan. Refrigerate, remove from pan when completely chilled.
