Stir all ingrediants together until crumbly. Press into the bottom and to the top of the sides lightly greased 9" springform pan. Place on a baking tray & bake for 10 minutes. Then cool while preparing other ingrediants.
Simmer all ingrediants over Medium heat, stirring occasionally, until most cranberries "pop", about 20 minutes. Cool, then chill completely.
reduce oven to 325 degrees. Beat cream cheese until smooth & fluffy. Gradually add sugar while beating, scrape sides often. Beat in cornstarch & vanilla. Add eggs 1 at a time, scraping well after each addition. Scrape into crust (only will go 1/2 way). Bake 30 minutes.
SOUR CREAM LAYER.
Stir sour cream, sugar & vanilla to blend. After cheesecake has baked, remove CAREFULLY & GENTLY dollop sour cream layer on cheesecae. Spread until even & return to oven for 30 minutes. (Mine took an extra 5-10 minutes to set.).
Chill overnight before garnishing.
To garnish, spread cranberries over top of chilled cheesecake & chill until ready to slice.
