In a medium-sized bowl, add the white chocolate chips and heavy cream. Place it in the microwave and heat in 30-second intervals, stirring inbetween each until the chocolate is completely melted. Set aside.
Reduce the oven temperature to 325 degrees Fahrenheit.
In a large mixing bowl, combine the cream cheese and sour cream. Beat with a hand mixer or in a stand mixer until combined and creamy.
Add the cornstarch and sugar, mixing again until completely combined.
Add one egg at a time, mixing only until the yellow of the egg has disappeared. During the addition of the last egg, add the vanilla and strawberry extract as well. Beat until smooth and creamy.
Mix in the melted white chocolate folding together until combined.
Add a couple of drops of pink food dye. (The amount will depend on the shade you desire.) Use a rubber spatula to fold in the color and mix until evenly distributed.
Pour the filling into the springform pan. Wrap the bottom with a double layer of foil.
Place this foil-wrapped pan in a baking dish filled with water about an inch deep.
Bake for 1 hour and 30 minutes. Then turn off the oven, open the door, and let the cheesecake sit in the warm oven for another hour.
Remove, cover, and refrigerate for 8 hours to chill.
When ready to serve, make the white chocolate ganache.
