I made a huge batch of Neufchatel last week, so was in search of a good cheesecake recipe when I found this one. Tea, it is wonderful! I had to convert measurements to Americanize them, and didn't have all of the ingredients that you used, so made some alterations, but my family really enjoyed this.
Here's my version:
Crust (I didn't have any chocolate biscuits and frequently use saltines, sugar and butter for a crust when graham cracker crust is called for):
1 tube saltine crackers, crushed fine
¼ cup cocoa
½ cup sugar
¼ cup melted butter
1 large (6.8 oz) Hershey’s Special Dark Chocolate bar
3 cups cream cheese
¾ cup sugar
1 Tbsp corn flour (I have masa flour for making tortillas)
1 ¼ cup vanilla yogurt (I didn’t have any sour cream)
1 tsp vanilla
The process was all the same, except I took out only about a cup and a half of the batter to mix with the melted chocolate, poured the plain filling into the pan, then dropped spoonsful of the chocolate batter onto the plain, then marbleized it by dragging a knife through the batter.
