Orange Cheese cake

I made this new york cheese cake with a kick of orange!
I used Oreo crumb instead of Graham cracker,
it gives a great color contrast to the cake
First of all, I substitute half amount of the sugar with orange jam.
I also added 2 Tsp of orange juice to the cake.

Here is the recipe:
Oreo crumb 120g
Unsalted butter (melted) 70g
Cream cheese (room temperature) 450g
Eggs 5
Orange juice 2 Tsp
Sugar 60g
Orange jam 60g
6inch baking pan

1- Mix melted butter with Oreo crumb, use a spoon to flatten it on the baking pan, keep in the freezer
2- Beat the cream cheese until light and fluffy, add sugar, continue mixing
3- Slowly add eggs to the cream cheese mixture one at a time, add orange juice and jam at the end and stir well
4- Pour the mixture in the baking pan
5- Bake in the hot water bath 260'F for 1 hr 15min
6- Run a pairing knife around the edge let it cool and put in the fridge

Topping
sugar 1/2 cup
water 2Tsp
5 slices of thin orange

1- Cook the sugar and water in medium heat, drop the orange slices
2- On a low heat cook for 15min, turn frequently
3- Cool on a baking sheet
