Engagement Cheesecake

Directions

Crush the graham crackers and mix with the butter.

Press into the bottom of a springform pan.

Blend the sour cream and cream cheese well and add the egg yolks (which have been beaten first) and the other ingredients.

Whip egg whites until stiff and fold cheese and yolk mixture in carefully.

Make sure it is all incorporated.

Pour onto crust and bake at 350℉ (180℃) for one hour.

Then leave door closed for one hour; and then oven door ajar for last hour (3 in all).

Cake is creamy and smooth and may crack a bit on top.

Good reason to make a strawberry topping.
